a300 also has greater functionality (2 RCA inputs, sub output with high pass crossover, tone controls, remote, bluetooth, dac) but really importantly: it has an internal power supply. I just got a v3 too and am really impressed. Great review, as always!
Glad to see you back here. You are my favorite audio reviewer! It is very difficult to describe the esoteric qualities of audio. You excel in providing relatable impressions in a clear and sensible manner. I bought the V3 a couple of months ago not expecting much but I am pleasantly surprised by the clarity and neutral sound of this tiny box. I listen almost exclusively to jazz and classical, especially classical piano. I have been using it with a Schiit Modi DAC and paired it with a bunch of speakers (I have lots) but I really like it with a pair of DCM CX-17s (old but really nice). I can't believe the value of this little guy. You can't go wrong with an amp that sounds this good for the money. I spend more money on a single transformer or tube for some of my home built amps and quite frankly the Fosi V3 put some of my efforts to shame. Time to start opamp rolling. I bought a second one so I can do a 1:1 comparison to the stock opamps. Keep up the good work!
I'm new to this hifi stereo thing and this video was so incredibly helpful. The ideas of how the amp sounds and the suggested pairing with other speakers for certain room sizes was great advice. Thanks !!
Thank you for your honest and detailed review! I also subscribed! Even though I didn't need it I just purchased the Fosi Audio V3 with the 48v power supply and the orange knob. Fosi Audio had a 20% off sale so it was a great value at $95.99 USD with free shipping. Best Wishes!
It would be nice / interesting if you could test Aiyima's new A07 Max amplifier. It is a direct competitor to Fosi V3, but it has "bridge mode" and you can use two (2) units as Monoblock amplifiers. It would be very interesting to know your opinion about this little Class D Monoblocks, and how much difference does it make in the music's Dynamic Range VS a single Fosi V3
Glad to see you back! Totally agree with you about the 48v power supply. Very noticeable difference in sound quality. I didn't need the extra power but it just adds better sonics. I got the 32v and ordered the 48v after the fact for around $50. I was able to do a direct comparison. Shocked how good this little amp sounds! Even the $140 I ended up spending for it with the added power supply I would have gladly paid double or more. I think it sounds that good. Very warm and punchy and full bass mids and treble in all the right places. I'm driving Mirage OM9 large tower omnidirectional speakers with it in my living room. No need for a subwoofer. I'm very pleased! Bargain is accurate!!!
I have used this tiny fosi audio v3 class d amp for two years. At this price this is simply the best class D amp. Thanks for your very detailed review!
Really put a smile on my face, thanks! Watched this at my PC in my little study, with the audio from the Fosi V3, SU-1, and a pair of Dali Oberon 1 (excellent small bookshelf speakers, which have been criticized for being a little bright). Your conclusion was absolutely spot on, thanks for the review!
You asked about Blu-Ray. I have flatscreen in a small TV room (under 2000 cu.ft.) that I occasionally watch a movie, but more often audio/video concert footage. Since I am wrapped up in stereo in other parts of the house, I bought a nice Yamaha HDMI surround sound bar with a subwoofer out and added a subwoofer. Long story short, I got it set up and sounding good; I had an old DVD player connected to the analog input on the TV, but then it died and I needed a player, so I bought a $75 LG Blu-ray player on Amazon that plays DVDs, or any CD in that size disc. I’ve been using that and it’s working great hooked into one of the HDMI inputs on the TV and plays through soundbar/sub system nicely. Even came with an HDMI cable. My super budget HT system, lol, of which can still be purchased for around $400 to $500 (not including the TV). I was lucky I got it all in for under $300 delivered through Amazon, and I didn’t buy everything at the same time, waiting for the right deal. Things seem to have changed in the last few years. It seems like getting great deals on subs is hard to come by these days.
Orange knobs ARE always worth the money. I won’t give up my ice cream though. Great fun. I enjoyed this a lot. Keep allowing your sense of humor to peak through.
Hi Srbo! Great seeing you at work again 💪💪💪 Nice little amp, I would say, lots of hype about it on YT. It does seem very limited in options (like a lot of similar Chinese products), but almost all YT reviewers agree on it's unusually good sound for the money. Nice to have heard your suggestion for the system, since I actually lack only the V3 to complete it 😂😂😂😂. Anyways, very nice and balanced review, as usual. Looking forward to seeing your next reviews. Cheers!
you've got a real talent for describing sounds and features! I recently got one of these and it pairs very well with my Schiit Mani, Freya+. I'm trying to decide if I like the separates more than just simply the Wiim Amp, which I thought sounded really solid.
Great video, I purchased the SMSL A300 based on one of you reviews and it's indeed a great amp bettering my trusted Mission Cyrus 1. I also purchased tha SMSL A0200 mk2 but found it was plagued with a faint high pitched noise in the background, this wasn't acceptable with my sensitive speakers, really annoying. I returned this unit and a replacement was sent but it too suffered from this issue. I returned the replacement and bought another SMSL A300 and at some point I will bridge them. I whish I held back for this review as I would have been tempted to by the fosi.
Glad you’re feeling better! Thanks for the review. I was planning on pairing it with the Elac Debut 2.0 5.2 in a small apartment, and you mentioned those speakers at the end. Now I don’t have to ask you how well they would pair. 😂
I have one on the way. Going to try them with my Braun L810s and my custom Folded Horn speakers. But they will probably be put to use in my kitchen system with OLD Telefunken speakers. Great review! Thanks.
I really think the Fosi Audio v3 is a good direct replacement for warmer sounding AB integrated amps like Marantz. My Marantz PM4001 died, so I took that as an opportunity to downsize with the Fosi v3. I was pleasantly surprised that they pair quite nicely with my existing pair of Monitor Audio BR1.
I have V3 for a while now paired it with SMSL SU-1 and KEF Q300 wow awesome nowadays you can have a good system that will not cost your arm i am amazed how V3 produce a ver good sound your review is spot on for V3 thanks
I have a fosi sub amp for a diy passive 12" sub i built. Works great. I bought my daughter the SMSL 300 and that thing was surprisingly good. Currently on one of my setups I have an older NAD 216 thx that i am sending in for service. I decided to get this amp as a stop gap because of the reviews and my experience with these newer budget amps. It will be pared with WIIM pro streamer, RME ADI 2 DAC fs, Schiit freya N preamp, and any of several speakers i like to change around.
Its worth mentioning its available without psu at all. So you can pick and choose what psu to use. I picked a meanwell drp 48v 10a psu. provides nice clean power. Also do yu plan in swapping in the sparkos or any different op amps? I've got opa 1622 in mine at the moment. deffo a step u from stock. others to try are opa2604, opa 1656 to mention a couple!
I *think* that the Sparkos SS3602 discrete op-amps fit in the V3, and I am fairly certain that it will take its sound quality up a notch or three. They obviously will add to the cost.
The two op-amps in the V3 are working as unity gain phase splitters for the TPA3255's balanced inputs. With unity gain, you can't expect much change or improvement by swapping op-amps. Fosi has promised "no fakes" for the NE5532 chips, so you should be good to go. I've tried my trusty old RC4558s and TL072s in the V3 (and A07). I can't confirm by testing since the difference is very slight, but they do seem to bring out the lower bass a bit more... and at less than $1.00 each, it's a pretty safe thing to try.
@@Douglas_Blake_579sorry to disagree but if you look at the TPA3255 datasheets you will find that the chip has a gain of 21.5dB, and measurements on the V3 have shown it has 26.5 dB. So the opamps provide 5dB extra gain. This is the reason why this amplifier uses 2 dual Opamps, otherwise they could get away with 1 dual opamps if its function were to create an inverted signal for Left and Right channels Now, would I spend $160 on those 2 Sparkos?. There are other good candidates for a fraction of that price:OPA1656 or OPA1612 on DIP8 adapters. On other amplifiers like Aiyima A07, A07 Pro or Max the total gain is even higher, 29dB. This means the opamps provide 7.5dB of extra gain. Therefore the opamp Rolling has a greater effect on those amplifiers.
Eventually I will try the Sparkos in mine. I’m convinced it can turn the V3 into a serious audiophile contender. Who cares if one op-amp costs as much as the amp if you end up with a wonderful sounding amp for 300$? It’s still ultra cheap by audiophile standards. I’ve decided to go first for the Oracle 02 op-amps. And I will see from there.
I picked this up with the upgraded power supply when they were on sale a couple of weeks ago. I’m using it with a couple of klipsch bookshelf speakers from the early aughts for my tv audio setup. It sounds good for the money.
I love your channel, and have turned a lot of people on to it. I am wondering if you would pop a couple Sparkos in that V3 amp and the Topping E50 and give us an update? I bought a few V3’s the other day to use with a miniDSP active system. I was in the industry for 21 years and have had really high end gear, but am pretty amazed at what one can get for such low dollars. I got the Topping E50 and the SU9 based on your recommendations, but have this low cost gear buying affliction (Ha!), so now have 3 V3’s. I own 1976 Cornwalls that I will mod to “Cornscalas,” and they are extremely unforgiving to sources, but all the gear I’ve mentioned works great with them. Buying these inexpensive Chifi gear and loving it is like finding an excellent wine for $15 bucks. I’m going to start my journey of tube rolling soon. I’ll get some Burr Browns: Opa2134s, Op1656s, Opa1612, and then the Sparkos a little later for the grand finale. Thank you for what you do! Peace!
Love your reviews. Too bad that the V3 Sub Out is useless, since it doesn't track the V3 volume control. Have you compared the SMSL AO300 to the A300 yet? Also, I have KEF LS50 METAs (and Magnepan LRS+). Which amp would was a better match for the METAs? The Fosi V3 or SMSL A300? Thanks for your help.
The lrs needs a lot of current !!. a used adcom 555-ll is perfect for the lrs, forget about the fosi. The adcom can put out 800 watts in 2 ohms, they don’t make amps like that anymore
Agreed. The budget friendly class AB amps from years ago are true power houses with heavy current output and ability to drive low impedance loads. Amps like the Adcom you mentioned, Threshold, Mondial, Gas Ampzilla, McCormack, Aragon, etc. They all had huge power supply sections with 2000VA transformers, which are very expensive to produce today. The cheap amps today regardless of Class type can't compete.@@cbayardelle
I have the Fosi V3 paired with a challenging B&W 685 with massive impedance drops, so the bass is not really great. Wold be better with an easier to drive speaker. Happy I got the 48V. Agree with your review.
I have the same problem. Fosi can drive floor stander definitive technology and wharfedale speakers easily with standard 32v power supply but my monitor audio bookshelf speaker is not happy with it. Bass performance is terrible.
@@tamayaytam This could be for a couple of reasons ... First what is the impedance of that bookshelf speaker ... if it dips under about 3.5 ohms the TPA3255 could be running into it's internal current limiting. Second there is the issue of speaker placement. You might accidentally have the bookshelf speakers in a bad spot for bass during your tests.
I have a separate stack from my main separates. I have my Turntable ,then a Fosi Box 3 phono pre amp , and then the Fosi V3 , with the 48v brick . going into my Definitive BP 8,s....and it sounds quite nice ..Fosi is definitely doing something right .and very affordable..what more can you ask for .. good review, by the way .Happy New Year.
Your comment about it not having enough impact for Electronic Music was key, since whatever I buy will be hooked up to a DJ system. Still looking for a good amp with slam but with airiness and sound stage as well.
I use a preamp as the input source, and feed everything through a DAC to the preamp. I've got a PC and 8 or 9 video game consoles as my primary sources, with the consoles all hooked up to a 16 port HDMI switch.
Yesterday my M-Audio AV40s died after 14 years and I enjoyed the way they sounded, no complaints. It was good enough for me. I ended up buying the Fosi V3 and the Elac Debut 5.2 which fit within my budget. I haven't got them yet but you made me get real excited, I can't wait to hear them. I don't have a DAC yet, so I might order the one you recommended at some point. Since I'm using them for my PC, my motherboard has a somewhat decent and shielded DAC built in so I'm hoping they'll sound good enough for what I need. But i'm also curious to see how the S.M.S.L SU-1 would sound as well. Not really sure what to do there. Its only $67 on amazon might be worth the investment.
I know that this is not the subject here, but i want to share with you my discovers: Here are my top ten hifi listenings: ALBUMS: 1. PATRICIA BARBER: Café blue or Clique! (32 bits or 4xDSD, a standard on hifi shows); 2. SHELBY LYNNE: Just a little lovin' (so in love...); 3. DIANA KRALL: Turn up the quiet (her voice so well recorded, microphone near her mouth...); 4. NILS LOFGREN: Acoustic live (the guitars so well recorded, another standard on hifi shows); 5. KEITH GREENINGER: Close to the soul (a pure DSD record); SONGS: 6. FINK: Perfect darkness (the subtlety of the percussion, the soft acoustic guitar, the relaxed voice... a delight!); 7. BRIAN BROMBERG: Elephants on ice skates (the bass and drum... just wow!); 8. GHOST RIDER: Make us stronger (a spectacular song for everyones who want to know the power of bass/electronic); 9. YELLO: Till tomorrow (bass and trumpet... at their best!); 10. THE FAIRFIELD FOUR: These bones (just for the fun to listen the lower bass voice you will ever listen to! 100% sure). Have fun!
I have something very similar, exactly the same box but with an additional on off switch at the front, it’s called BRZ hifi tpa3118 , I feed it with some 18v p.s I found at home. bought it some 3 years ago at $80 . It’s in the kitchen, used with an FM radio so I never tested it’s musical abilities with my main speakers, I might do it one day.
I've been listening to this amp with the 48v for two months and I'm very, very surprised. Silence, once connected, is absolute. At first I couldn't believe that sound could fill my 40-square-meter music room. I have, thanks to Srboljub, an Rpi2aes light and a SMSL D0 200 MK II DAC that acts also as a preamp to manage the volume and the V3 at its maximum volume. I still use my old REGA ELA MKIII speakers, awaiting replacement for the Falcon Q7 kit... I read and read about the possibility of swapping out op amps, and eventually decided to swap out the original op-amps in favor of the humble-priced Opa1622. To hear is to believe. In a few days, the sound became more transparent, more timbral, softer and easier to hear and over all, the soundstage is now more wide and precise. I must say that the original op-amps are really clung like a bird of prey to the base and have been deformed when removed. My clumsiness, but have read other people have had the same problem. Given how it sounds now, I don't regret it much. Now, Fosi is about to launch his First Dual-Mode Balanced Amplifier ZA3... I'd like to try them in a pair of monoblocks, but I don't like to much the way they are placing switches, etc. I was expecting a pair of nice monoblocks as simple as the V3 but without knobs...
I also found the original Opamps to be mounted very tight, swapped them out for a pair of OPA2134. V3 is fed by a cheap Denon turntable with inbuilt phono stage. Small Denon bookshelf speakers, but damn it sounds good 👍
With some other opamps like opa 1612 or 1622 i don't think there will be a lot of difference with the SMSL. Fosi is coming with a new version of this (za3)with a real sub out and a monoblock switch. I am really interested in a pair of those.
How would your recomended component setup compare to an integrated approach such as KEF LS11? - I am looking for speakers for a Mac (so cant be too large) - Many Thanks - appreciate the style of your presentation ..
By Measurement ... 32 volt supply ... 50w rms per channel on 8 ohms, 95 w/ch on 4 ohms with less than 0.1% distortion. 1.2v input for clipping 48 volt supply ... 100w rms per channel on 8 ohms, 180 w/ch on 4 ohms with less than 0.3% distortion. 2.2v input for clipping The gain is fixed, so switching power supplies won't make it louder, but it will give you more headroom before clipping starts. If you want to know what the TPA3255 chip can do, cut it loose on a pair of "workhorse" speakers like the Heresy or L-100 ... it's a real treat. Drives most towers to surprising volume.
Pozdrav i veliko poštovanje prema energiji koja se ulaže, bi se Hi Fi problematika približila onima koji u taj svet ulaze. Imam jedno pitanje upravo 13:20 u vezi uparivanja na osnovu svih recenzija koje sam pogledao. Kako na osnovu slušnog iskustava ,zvuči kombinacija? -Project pre box S2 digital -Fosi V3 monoblokovi -Triangle Borea BR03 Ozbiljno sam se zagreao da tom kombinacijom zamenim. Denona PMA 560 i I Tannoy Merkuri 1 Uglavnom slušam Radio nekada analogno. A danas sa neta i Radio Gardena. Jazz, Clasika, filmska i etno muzika. Uglavnom akustika. S obzirom da za te pare ne mogu dobiti High and muzičku liniju, makar bi dobio Micro End muzičku liniju.😂 Ne znam i koliko bolju od predhodne?
Hi IIWI, how are ya doin, I just bought AKG K702, I need a suggestion from you for a good amp for it. Superb clarity, details, soundstage etc but two problems with it. Thin note weight and while the bass is very tight, not much extension or depth in bass. Running it off of a dongle Ibasso DC04 Pro for now which has like 125 mW in single ended
That’s a great review. I have two Fosi V3s on the way, and I’m going to try them in my main system which is DIY horn speakers (think Klipsch LaScala on steroids, 105dB average sensitivity) bi-amped with active crossover. I’m genuinely interested in trying these little cheap marvels in more upmarket / demanding system rather than the usual « 79$ DAC, 200$ speakers ». I’m a strong believer that with a little care (and a change of op amps, really in a revealing system such as mine NE5532 sound like crap especially the cheap versions used by Chinese companies) and in the right system (one that doesn’t put any strain on the amplifier) well designed tiny amps like this one can be extremely satisfying. I have four Oracle 02 OM-amps on the way to replace the NE5532.
What would you suggest as a good step up from the V3 for better bass control and clarity? It sounds better than my BT20Apro, but lacks the kick. While it does have more low end than the AO200, it just sounds a little muddy to me. The V3 48v5a is currently paired with an SMSL D-6 and SVS Ultra Bookshelf.
I have used with a tube preamp - also changed the opamp - and I truly noticed difference - and one that I preferred - as you say, maybe more a near-field amp - but it is pretty amazing.
Can you describe the sound with tube preamp? Like soundstage, instrument separation, is there a full bodied sound present? I think a tube pre / power combo is more effective than V3 itself.
Hi - I bought V3 with additional opamps - and whilst taking the originals out was not fun - I was happy with the alteration in sound - and the opamps I put in came via FOSI - and I believe they are OPA2604. I have tube preamps - and recently, I have gone toward budget near-field setups - as my main stuff is back in Europe. I settled on a preamp with Mullards as tubes and rectifier with the V3. Speakers are extremely sensitive single drivers ( Maybe not the best with such a meaty little amp.). I was delighted with the sound of this setup. I like some tube colouration, I think - and the FOSI is maybe surgically neutral (ergo, perhaps too good - for me!). Certainly, a dynamic set-up - and I feel more naturalistic, more 'rounded' than before - for me it became way more engaging to listen to. I put the preamp volume high - meaning the FOSI must be low - maybe I am doing that wrong ... I Apologise if this is all word salad - as it is hard to describe hifi - but it changed, and I liked the new sound! Take care. @@computeraudiophile9590
Great review as always. i have both smsl a300 and fosi v3. . fosi v3 sounds very good ( dynamic /natural but non fatiguing) with small old Q Acoustics 2010I Compact Bookshelf Speaker . want try with my triangle borea BRO2 which are connected to topping PA5 amp.
@@marishkumar607 I personally would not use a preamp with the fosi. the amp needs a few hours of burn in before it works at maximum volume. it gets louder after some use. I have the 48 volt edition.
👨🏻Good review. I have been using Class D head amps for bass guitar, and not much wrong with it; just takes a higher wattage rating amp that’s not driven hard to it’s rating to be similar.
On UK Amazon the 48 volt is E153 I own an old IFI micro ISD with a preamp facility could I use this via the coaxial connects what does the pre-out on the FOSI do?

Which speaker would you choose borea 03 vs kef q150 ?
There is a Turkish channel that suggests kef q150. As a reference, I am not happy with fosi while driving monitor audio bronze 2 bookshelf speakers. It is lacking on bass. I am powering it with 32v power supply though.
The amp puts out 161 watts in four ohm, & 191 watts peak, that a lot of headroom. That’s with the 48v power supply. Audioscience reviewed the amp, & the smsl a300 puts out less then 100 watts in 4ohm, but in bridged mode 400 watts but with high distortion & terrible frequency changes.
Add a simple subwoofer, not an expensive one. I have a Parts-Express 12" Sub that cost me ~ 250 USD about a decade ago (including international shipping), and it makes a big difference in my stereo system. Your system should be balance, don't over -spent on a Sub. I would recommend you take a look at Emotiva 's less expensive Subs, that have good power and a high-speed / low-pass filter built-in
Few things to consider. V3 pre out cannot control the volume of the subwoofer, it is just a pass through, subwoofer volume should be controlled separately. And you need to get a subwoofer with high level input to connect with the V3 preout.
It's not controlled by the volume control so, useless for a sub. Actually it's more useful as a secondary input, since it's directly wired to the RCA jacks.
Al those Chinese amps, make speakers to bright or dull depending on frequencies especially on 4 ohm low efficient speakers. Like an elac ub5 that needs more then 200 watts per channel to make them sing.
I have A07 with some tweak (caps nichicon 2x2200uf instead of 2x1000uf, etc) pair to E30 old. If someday want upgrade, I might choose A07 Max rather then V3
@@iiWiReviews very nice, I have V3 with SMSL SU-1 and Dynaudio Emit M10 in near field listening. Your reply helped me a lot. Have a great week and thank you.
Your question is answered already but I would like to give you another user experience. I am driving my monitor audio bronze 2 bookshelf speakers with fosi powered by 32v power supply. Speakers volume are OK. But they can not go deep in bass and that reduces the sound quality because they don't produce every detail. Meantime I drive 2 different sets of floor standers. Everything is OK. Unfortunately I doubt near field listening will be satisfactory.
Unfortunately the subwoofer output does not change along with V3 volume adjustments, rendering the sub out as useless. Hopefully they fix this with Fosi za3.
Yes, I believe that would work. But it routes the main speaker through the sub's xover to roll off the main speaker's bass. It eliminates the option of running the main speaker fullrange and untouched. But certainly an option, thanks.@@Douglas_Blake_579
Без проблем. А если поменяете операционные усилители, получите очень взрослый звук. У меня пара Fosi ZA3 в моно-режиме с операционниками Sparkos SS3602, играют заметно интереснее имеющегося у меня Atoll IN100, с такой же широкой сценой, динамикой, но прозрачнее и с более высокой детализацией.
It would have been Nice if you could've tested it with different opamps. Oh and za3 is already on kickstarter. Measurements aren't as good but otherwise seems like and upgrade on every front.
under that logic, i wouldn't watch reviews at all. I'd just buy everything and test it myself. 🤦♂He's done it before with other gear, so why not with this one? Not complaining, just saying...
@@JoseFerreira-zb7wh well that’s a little extreme but I get what you’re saying.. I don’t know what to tell you, maybe it’s not something that a lot of people bother with .. you know, they want to know that the product stands on its own merit without modification, or they’re unmotivated or not competent,, but then again, there is a small percentage of people who want to do those kinds of things .. me, I can go either way, it just depends on what it costs, what I have to do, is it worth it to me, or worth the difference in performance or whatever, so I hear you. I kind of thought maybe he just didn’t bother because it’s $100 amplifier that doesn’t really have any flexibility I mean it’s just a brick, so I guess he figured it was more of a tinkerer kind of product and left the exercise for those that wanted to go there.
I couldn't resist adding the Sparkos and a beefier (more current capable) 48V power supply, and, well, that little bastard is going to stay. I even may have plans to replace the binding posts and some internal wiring. It's a hobby ;-)
@@Douglas_Blake_579Yeah, I would really like to hear it. I want to be impressed. In general terms I feel stereo gear is overpriced. If this amp is as good as been mentioned I feel that is a truly great accomplishment. Which value minded people reap the benefits of.
@@NosEL34 Most online vendors have a 30 day return policy... so the only thing stopping you is that initial cash outlay. If you are impressed, YAY! If not, just send it back. I use a number of different TPA3255 based amplifiers in a "soundbar killer" system I sell to friends and friends of friends. I will say that I am genuinely impressed by their performance and I'm pretty fussy about sound quality. The chip itself was developed by TI for pro-audio applications in sound reinforcement and studio monitors. You will also find them in high end AVR systems and even mid-to-high end stereo systems. Take the leap ... answer your own questions!
I strongly suspect the build quality and durability of these chinese amp. Just at 250 one can get denon m41 or yamaha 202. Also this v3 has no bluetooth and low power.
Never heard the V3, but a day after getting the Fosi Audio ZA3, I gave my A07 to a friend and sent an AO200 MKII back. Obviously a lot depends on how you use it and speaker pairings, etc., but doing the closest I could to an a/b comparison, I thought the ZA3 absolutely smoked the other two. Might give it a listen if you have a chance.
I upgraded the op amps on the a07 max, first to sparkos then the muse02. The sparkos sounded too analytical in my system. The muse are wonderful sounding. I've ordered the za3 so I can get a complete 2.1 system. Plan to try the muse and sparkos op amps as well.
a300 also has greater functionality (2 RCA inputs, sub output with high pass crossover, tone controls, remote, bluetooth, dac) but really importantly: it has an internal power supply. I just got a v3 too and am really impressed.
Great review, as always!

It would be very interesting to know your opinion about this little Class D Monoblocks, and how much difference does it make in the music's Dynamic Range VS a single Fosi V3
Glad to see you back! Totally agree with you about the 48v power supply. Very noticeable difference in sound quality. I didn't need the extra power but it just adds better sonics. I got the 32v and ordered the 48v after the fact for around $50. I was able to do a direct comparison. Shocked how good this little amp sounds! Even the $140 I ended up spending for it with the added power supply I would have gladly paid double or more. I think it sounds that good. Very warm and punchy and full bass mids and treble in all the right places. I'm driving Mirage OM9 large tower omnidirectional speakers with it in my living room. No need for a subwoofer. I'm very pleased! Bargain is accurate!!!
Your review was absolutely correct. My Cornwalls never sounded so coherent and correct with this great ammp.
Really,what pre amp are u using
Excellent vid. My Tradutto sounds so good, it seems to dig deeper as time goes. Good to see you. Stay well. Cool runnings
Thanks for your generous help! 👍👍👍

ThanksMuch! Hope you're feeling better.
I have used this tiny fosi audio v3 class d amp for two years. At this price this is simply the best class D amp. Thanks for your very detailed review!
Really put a smile on my face, thanks! Watched this at my PC in my little study, with the audio from the Fosi V3, SU-1, and a pair of Dali Oberon 1 (excellent small bookshelf speakers, which have been criticized for being a little bright). Your conclusion was absolutely spot on, thanks for the review!
I have exactly the same setup
@@MegaEpstein me too
You asked about Blu-Ray. I have flatscreen in a small TV room (under 2000 cu.ft.) that I occasionally watch a movie, but more often audio/video concert footage. Since I am wrapped up in stereo in other parts of the house, I bought a nice Yamaha HDMI surround sound bar with a subwoofer out and added a subwoofer. Long story short, I got it set up and sounding good; I had an old DVD player connected to the analog input on the TV, but then it died and I needed a player, so I bought a $75 LG Blu-ray player on Amazon that plays DVDs, or any CD in that size disc. I’ve been using that and it’s working great hooked into one of the HDMI inputs on the TV and plays through soundbar/sub system nicely. Even came with an HDMI cable. My super budget HT system, lol, of which can still be purchased for around $400 to $500 (not including the TV). I was lucky I got it all in for under $300 delivered through Amazon, and I didn’t buy everything at the same time, waiting for the right deal. Things seem to have changed in the last few years.
It seems like getting great deals on subs is hard to come by these days.
Orange knobs ARE always worth the money. I won’t give up my ice cream though. Great fun. I enjoyed this a lot. Keep allowing your sense of humor to peak through.
Hi Srbo!
Great seeing you at work again 💪💪💪
Nice little amp, I would say, lots of hype about it on YT. It does seem very limited in options (like a lot of similar Chinese products), but almost all YT reviewers agree on it's unusually good sound for the money.
Nice to have heard your suggestion for the system, since I actually lack only the V3 to complete it 😂😂😂😂.
Anyways, very nice and balanced review, as usual. Looking forward to seeing your next reviews.
Cheers!
you've got a real talent for describing sounds and features! I recently got one of these and it pairs very well with my Schiit Mani, Freya+. I'm trying to decide if I like the separates more than just simply the Wiim Amp, which I thought sounded really solid.
First video I have watched of yours, I’m very impressed, have subscribed, thank you.
Good rev I bought SMSL A300 after I saw your review.
Great video, I purchased the SMSL A300 based on one of you reviews and it's indeed a great amp bettering my trusted Mission Cyrus 1. I also purchased tha SMSL A0200 mk2 but found it was plagued with a faint high pitched noise in the background, this wasn't acceptable with my sensitive speakers, really annoying. I returned this unit and a replacement was sent but it too suffered from this issue. I returned the replacement and bought another SMSL A300 and at some point I will bridge them. I whish I held back for this review as I would have been tempted to by the fosi.
Glad you’re feeling better! Thanks for the review. I was planning on pairing it with the Elac Debut 2.0 5.2 in a small apartment, and you mentioned those speakers at the end. Now I don’t have to ask you how well they would pair. 😂
Orange knobs always worth their money.... thing to write down :) Thank you for review.
I have one on the way. Going to try them with my Braun L810s and my custom Folded Horn speakers. But they will probably be put to use in my kitchen system with OLD Telefunken speakers. Great review! Thanks.
Orange Knobs are always worth their money. Best line ever. LOL
I really think the Fosi Audio v3 is a good direct replacement for warmer sounding AB integrated amps like Marantz.
My Marantz PM4001 died, so I took that as an opportunity to downsize with the Fosi v3. I was pleasantly surprised that they pair quite nicely with my existing pair of Monitor Audio BR1.
Muchas gracias por subtitular el video en español. Thank you very much for subtitling the video in Spanish.

I have V3 for a while now paired it with SMSL SU-1 and KEF Q300 wow awesome nowadays you can have a good system that will not cost your arm i am amazed how V3 produce a ver good sound your review is spot on for V3 thanks
I have a fosi sub amp for a diy passive 12" sub i built. Works great. I bought my daughter the SMSL 300 and that thing was surprisingly good. Currently on one of my setups I have an older NAD 216 thx that i am sending in for service. I decided to get this amp as a stop gap because of the reviews and my experience with these newer budget amps. It will be pared with WIIM pro streamer, RME ADI 2 DAC fs, Schiit freya N preamp, and any of several speakers i like to change around.
So glad my audio vampire is back.like hearing your voice.
I’m still spinning 💿….on a Denon 3520 “The Beast “…going strong over 3 decades of loyal service.
Its worth mentioning its available without psu at all. So you can pick and choose what psu to use. I picked a meanwell drp 48v 10a psu. provides nice clean power. Also do yu plan in swapping in the sparkos or any different op amps? I've got opa 1622 in mine at the moment. deffo a step u from stock. others to try are opa2604, opa 1656 to mention a couple!
I *think* that the Sparkos SS3602 discrete op-amps fit in the V3, and I am fairly certain that it will take its sound quality up a notch or three. They obviously will add to the cost.
The two op-amps in the V3 are working as unity gain phase splitters for the TPA3255's balanced inputs. With unity gain, you can't expect much change or improvement by swapping op-amps. Fosi has promised "no fakes" for the NE5532 chips, so you should be good to go.
I've tried my trusty old RC4558s and TL072s in the V3 (and A07). I can't confirm by testing since the difference is very slight, but they do seem to bring out the lower bass a bit more... and at less than $1.00 each, it's a pretty safe thing to try.
@@Douglas_Blake_579sorry to disagree but if you look at the TPA3255 datasheets you will find that the chip has a gain of 21.5dB, and measurements on the V3 have shown it has 26.5 dB. So the opamps provide 5dB extra gain. This is the reason why this amplifier uses 2 dual Opamps, otherwise they could get away with 1 dual opamps if its function were to create an inverted signal for Left and Right channels
Now, would I spend $160 on those 2 Sparkos?. There are other good candidates for a fraction of that price:OPA1656 or OPA1612 on DIP8 adapters.
On other amplifiers like Aiyima A07, A07 Pro or Max the total gain is even higher, 29dB. This means the opamps provide 7.5dB of extra gain. Therefore the opamp Rolling has a greater effect on those amplifiers.
Eventually I will try the Sparkos in mine. I’m convinced it can turn the V3 into a serious audiophile contender. Who cares if one op-amp costs as much as the amp if you end up with a wonderful sounding amp for 300$? It’s still ultra cheap by audiophile standards.
I’ve decided to go first for the Oracle 02 op-amps. And I will see from there.
@@FrancoisLeopold Did you get better sound by switching to discete opamp?
I use an Oppo BluRay player for both my HD movie collection and I use it to play CDs through my theater audio system.
I picked this up with the upgraded power supply when they were on sale a couple of weeks ago. I’m using it with a couple of klipsch bookshelf speakers from the early aughts for my tv audio setup. It sounds good for the money.
I love your channel, and have turned a lot of people on to it. I am wondering if you would pop a couple Sparkos in that V3 amp and the Topping E50 and give us an update? I bought a few V3’s the other day to use with a miniDSP active system. I was in the industry for 21 years and have had really high end gear, but am pretty amazed at what one can get for such low dollars. I got the Topping E50 and the SU9 based on your recommendations, but have this low cost gear buying affliction (Ha!), so now have 3 V3’s. I own 1976 Cornwalls that I will mod to “Cornscalas,” and they are extremely unforgiving to sources, but all the gear I’ve mentioned works great with them. Buying these inexpensive Chifi gear and loving it is like finding an excellent wine for $15 bucks. I’m going to start my journey of tube rolling soon. I’ll get some Burr Browns: Opa2134s, Op1656s, Opa1612, and then the Sparkos a little later for the grand finale. Thank you for what you do! Peace!
I missed that you didn't test it with the Sparkos SS3602 like you did with the Aune X8 for such an improvement!
Love your reviews. Too bad that the V3 Sub Out is useless, since it doesn't track the V3 volume control.
Have you compared the SMSL AO300 to the A300 yet?
Also, I have KEF LS50 METAs (and Magnepan LRS+). Which amp would was a better match for the METAs? The Fosi V3 or SMSL A300? Thanks for your help.
The lrs needs a lot of current !!. a used adcom 555-ll is perfect for the lrs, forget about the fosi. The adcom can put out 800 watts in 2 ohms, they don’t make amps like that anymore
Agreed. The budget friendly class AB amps from years ago are true power houses with heavy current output and ability to drive low impedance loads. Amps like the Adcom you mentioned, Threshold, Mondial, Gas Ampzilla, McCormack, Aragon, etc. They all had huge power supply sections with 2000VA transformers, which are very expensive to produce today. The cheap amps today regardless of Class type can't compete.@@cbayardelle
I have the Fosi V3 paired with a challenging B&W 685 with massive impedance drops, so the bass is not really great. Wold be better with an easier to drive speaker. Happy I got the 48V. Agree with your review.
See if you can get it hooked up to a pair of Heresys or L-100s ... very impressive.
@Douglas_Blake_579 It is pretty hard to find those speakers in Sri Lanka. Will watch out. Thanks
@@enricolisk1357
Pretty much any floor stander... The point is that small amplifier does not mean small speakers.
I have the same problem. Fosi can drive floor stander definitive technology and wharfedale speakers easily with standard 32v power supply but my monitor audio bookshelf speaker is not happy with it. Bass performance is terrible.
@@tamayaytam
This could be for a couple of reasons ...
First what is the impedance of that bookshelf speaker ... if it dips under about 3.5 ohms the TPA3255 could be running into it's internal current limiting.
Second there is the issue of speaker placement. You might accidentally have the bookshelf speakers in a bad spot for bass during your tests.
I have a separate stack from my main separates. I have my Turntable ,then a Fosi Box 3 phono pre amp , and then the Fosi V3 , with the 48v brick . going into my Definitive BP 8,s....and it sounds quite nice ..Fosi is definitely doing something right .and very affordable..what more can you ask for .. good review, by the way .Happy New Year.
Your comment about it not having enough impact for Electronic Music was key, since whatever I buy will be hooked up to a DJ system. Still looking for a good amp with slam but with airiness and sound stage as well.
I use a preamp as the input source, and feed everything through a DAC to the preamp. I've got a PC and 8 or 9 video game consoles as my primary sources, with the consoles all hooked up to a 16 port HDMI switch.
Yesterday my M-Audio AV40s died after 14 years and I enjoyed the way they sounded, no complaints. It was good enough for me. I ended up buying the Fosi V3 and the Elac Debut 5.2 which fit within my budget. I haven't got them yet but you made me get real excited, I can't wait to hear them. I don't have a DAC yet, so I might order the one you recommended at some point. Since I'm using them for my PC, my motherboard has a somewhat decent and shielded DAC built in so I'm hoping they'll sound good enough for what I need. But i'm also curious to see how the S.M.S.L SU-1 would sound as well. Not really sure what to do there. Its only $67 on amazon might be worth the investment.
I know that this is not the subject here, but i want to share with you my discovers:
Here are my top ten hifi listenings:
ALBUMS:
1. PATRICIA BARBER: Café blue or Clique! (32 bits or 4xDSD, a standard on hifi shows);
2. SHELBY LYNNE: Just a little lovin' (so in love...);
3. DIANA KRALL: Turn up the quiet (her voice so well recorded, microphone near her mouth...);
4. NILS LOFGREN: Acoustic live (the guitars so well recorded, another standard on hifi shows);
5. KEITH GREENINGER: Close to the soul (a pure DSD record);
SONGS:
6. FINK: Perfect darkness (the subtlety of the percussion, the soft acoustic guitar, the relaxed voice... a delight!);
7. BRIAN BROMBERG: Elephants on ice skates (the bass and drum... just wow!);
8. GHOST RIDER: Make us stronger (a spectacular song for everyones who want to know the power of bass/electronic);
9. YELLO: Till tomorrow (bass and trumpet... at their best!);
10. THE FAIRFIELD FOUR: These bones (just for the fun to listen the lower bass voice you will ever listen to! 100% sure).
Have fun!
I have something very similar, exactly the same box but with an additional on off switch at the front, it’s called BRZ hifi tpa3118 , I feed it with some 18v p.s I found at home. bought it some 3 years ago at $80 . It’s in the kitchen, used with an FM radio so I never tested it’s musical abilities with my main speakers, I might do it one day.
48V ..right choice!
Significaly richer sound!
BTW...A very nice review.
I've been listening to this amp with the 48v for two months and I'm very, very surprised. Silence, once connected, is absolute. At first I couldn't believe that sound could fill my 40-square-meter music room. I have, thanks to Srboljub, an Rpi2aes light and a SMSL D0 200 MK II DAC that acts also as a preamp to manage the volume and the V3 at its maximum volume. I still use my old REGA ELA MKIII speakers, awaiting replacement for the Falcon Q7 kit...
I read and read about the possibility of swapping out op amps, and eventually decided to swap out the original op-amps in favor of the humble-priced Opa1622. To hear is to believe. In a few days, the sound became more transparent, more timbral, softer and easier to hear and over all, the soundstage is now more wide and precise.
I must say that the original op-amps are really clung like a bird of prey to the base and have been deformed when removed. My clumsiness, but have read other people have had the same problem. Given how it sounds now, I don't regret it much.
Now, Fosi is about to launch his First Dual-Mode Balanced Amplifier ZA3... I'd like to try them in a pair of monoblocks, but I don't like to much the way they are placing switches, etc. I was expecting a pair of nice monoblocks as simple as the V3 but without knobs...
I also found the original Opamps to be mounted very tight, swapped them out for a pair of OPA2134. V3 is fed by a cheap Denon turntable with inbuilt phono stage. Small Denon bookshelf speakers, but damn it sounds good 👍
With some other opamps like opa 1612 or 1622 i don't think there will be a lot of difference with the SMSL. Fosi is coming with a new version of this (za3)with a real sub out and a monoblock switch. I am really interested in a pair of those.
I woule like to see your review of the new SMSL AO 300 !
I bought this amp on a black friday sale with the 48v psu, it was $89 including shipping, as I recall
How would your recomended component setup compare to an integrated approach such as KEF LS11? - I am looking for speakers for a Mac (so cant be too large) - Many Thanks - appreciate the style of your presentation ..
No ice-cream - better knob...
"Life coaches" everywhere will be stealing that! 😂😂😂
By Measurement ...
32 volt supply ... 50w rms per channel on 8 ohms, 95 w/ch on 4 ohms with less than 0.1% distortion. 1.2v input for clipping
48 volt supply ... 100w rms per channel on 8 ohms, 180 w/ch on 4 ohms with less than 0.3% distortion. 2.2v input for clipping
The gain is fixed, so switching power supplies won't make it louder, but it will give you more headroom before clipping starts.
If you want to know what the TPA3255 chip can do, cut it loose on a pair of "workhorse" speakers like the Heresy or L-100 ... it's a real treat. Drives most towers to surprising volume.

Hi IIWI, how are ya doin, I just bought AKG K702, I need a suggestion from you for a good amp for it. Superb clarity, details, soundstage etc but two problems with it. Thin note weight and while the bass is very tight, not much extension or depth in bass. Running it off of a dongle Ibasso DC04 Pro for now which has like 125 mW in single ended
Using 2 units in bridge mode will bring more power but will it bring a better sound quality ? More separation ? More dynamic ?
Fosi can not work as mono. So no bridge capability. You can only use as biamp only.
That’s a great review. I have two Fosi V3s on the way, and I’m going to try them in my main system which is DIY horn speakers (think Klipsch LaScala on steroids, 105dB average sensitivity) bi-amped with active crossover.
I’m genuinely interested in trying these little cheap marvels in more upmarket / demanding system rather than the usual « 79$ DAC, 200$ speakers ».
I’m a strong believer that with a little care (and a change of op amps, really in a revealing system such as mine NE5532 sound like crap especially the cheap versions used by Chinese companies) and in the right system (one that doesn’t put any strain on the amplifier) well designed tiny amps like this one can be extremely satisfying.
I have four Oracle 02 OM-amps on the way to replace the NE5532.
What would you suggest as a good step up from the V3 for better bass control and clarity? It sounds better than my BT20Apro, but lacks the kick. While it does have more low end than the AO200, it just sounds a little muddy to me. The V3 48v5a is currently paired with an SMSL D-6 and SVS Ultra Bookshelf.
I have used with a tube preamp - also changed the opamp - and I truly noticed difference - and one that I preferred - as you say, maybe more a near-field amp - but it is pretty amazing.
Can you describe the sound with tube preamp? Like soundstage, instrument separation, is there a full bodied sound present? I think a tube pre / power combo is more effective than V3 itself.
Hi - I bought V3 with additional opamps - and whilst taking the originals out was not fun - I was happy with the alteration in sound - and the opamps I put in came via FOSI - and I believe they are OPA2604. I have tube preamps - and recently, I have gone toward budget near-field setups - as my main stuff is back in Europe. I settled on a preamp with Mullards as tubes and rectifier with the V3. Speakers are extremely sensitive single drivers ( Maybe not the best with such a meaty little amp.). I was delighted with the sound of this setup. I like some tube colouration, I think - and the FOSI is maybe surgically neutral (ergo, perhaps too good - for me!). Certainly, a dynamic set-up - and I feel more naturalistic, more 'rounded' than before - for me it became way more engaging to listen to. I put the preamp volume high - meaning the FOSI must be low - maybe I am doing that wrong ... I Apologise if this is all word salad - as it is hard to describe hifi - but it changed, and I liked the new sound! Take care. @@computeraudiophile9590

Seja bem vindo de novo. Um abraço de Portugal.
I couldn't pass on this one. Mine unit is stuck in customs for about 3 weeks though 😅. Definitely will try with sparkos ss3602 at some point too.
These are often recommended to drive hight channels if your AVR has 11 channels but can only drive 9 with the internal amps.
👨🏻Good review.
I have been using Class D head amps for bass guitar, and not much wrong with it; just takes a higher wattage rating amp that’s not driven hard to it’s rating to be similar.
On UK Amazon the 48 volt is E153 I own an old IFI micro ISD with a preamp facility could I use this via the coaxial connects what does the pre-out on the FOSI do?
Which speaker would you choose borea 03 vs kef q150 ?
There is a Turkish channel that suggests kef q150. As a reference, I am not happy with fosi while driving monitor audio bronze 2 bookshelf speakers. It is lacking on bass. I am powering it with 32v power supply though.
The amp puts out 161 watts in four ohm, & 191 watts peak, that a lot of headroom. That’s with the 48v power supply. Audioscience reviewed the amp, & the smsl a300 puts out less then 100 watts in 4ohm, but in bridged mode 400 watts but with high distortion & terrible frequency changes.
How does this compare to the Aiyama ao7?
Can you review the za3 and do the sparcos op amp swap and tell us your thoughts
The Amp sounds very very good with headphones also..... just get the Hifiman HE adaptor to hook it up and then enjoy...
Yes I use a CD player. I also use a turntable.
I have elac b6 plus smsl su1 plus fosi v3. Are they good if i add subwoofer like svs sb1000 pro?
Add a simple subwoofer, not an expensive one. I have a Parts-Express 12" Sub that cost me ~ 250 USD about a decade ago (including international shipping), and it makes a big difference in my stereo system. Your system should be balance, don't over -spent on a Sub. I would recommend you take a look at Emotiva 's less expensive Subs, that have good power and a high-speed / low-pass filter built-in
Few things to consider. V3 pre out cannot control the volume of the subwoofer, it is just a pass through, subwoofer volume should be controlled separately. And you need to get a subwoofer with high level input to connect with the V3 preout.
nice review. bt20a pro review please.
As I see the picture of that amp, there is pre out (i assume it is 3.5 mm). Perhaps you can connect it to subwoofer, to increase the dynamics.
It's not controlled by the volume control so, useless for a sub. Actually it's more useful as a secondary input, since it's directly wired to the RCA jacks.
Is there I can listen to the music with this class D amp?
This amp is tested by audioscience it puts out over 191 watts at 1 percent distortion in 4 ohms peak power
I could have sworn I saw another reviewer mention that the orange knob was included. Seems a bit overpriced but I'd still pay the ten bucks for it.
Al those Chinese amps, make speakers to bright or dull depending on frequencies especially on 4 ohm low efficient speakers. Like an elac ub5 that needs more then 200 watts per channel to make them sing.
I have A07 with some tweak (caps nichicon 2x2200uf instead of 2x1000uf, etc) pair to E30 old. If someday want upgrade, I might choose A07 Max rather then V3
Hello, can it drive well the ls50? thank you.
In a nier field listening it would be OK. For anything else I wouldn't pair them. LS50 are not an easy load.
@@iiWiReviews very nice, I have V3 with SMSL SU-1 and Dynaudio Emit M10 in near field listening. Your reply helped me a lot. Have a great week and thank you.
Your question is answered already but I would like to give you another user experience. I am driving my monitor audio bronze 2 bookshelf speakers with fosi powered by 32v power supply. Speakers volume are OK. But they can not go deep in bass and that reduces the sound quality because they don't produce every detail. Meantime I drive 2 different sets of floor standers. Everything is OK. Unfortunately I doubt near field listening will be satisfactory.
@@tamayaytam thank you.
Good review but your comparison is not fair. Smsl a300 is pretty different device with much wider functionality.
Can I use this amp as the power for a DAC for a headphone
Aiyima has a Fosi V3 killer. The Aiyima A07 max.
Does the pre-out have variable output for a subwoofer or is it fixed volume?
Unfortunately the subwoofer output does not change along with V3 volume adjustments, rendering the sub out as useless. Hopefully they fix this with Fosi za3.
@@geevee1045There's maybe a workaround:
get a sub with high-level inputs and outputs and conect your amp and speakers to it that way
I guess if you use a preamp with it the sub out would work accordingly. But that's an extra cost
Use your sub's high level inputs and drive it off the speaker wires.
Yes, I believe that would work. But it routes the main speaker through the sub's xover to roll off the main speaker's bass. It eliminates the option of running the main speaker fullrange and untouched. But certainly an option, thanks.@@Douglas_Blake_579

I kind of thought maybe he just didn’t bother because it’s $100 amplifier that doesn’t really have any flexibility I mean it’s just a brick, so I guess he figured it was more of a tinkerer kind of product and left the exercise for those that wanted to go there.
Please review ifi lan isilencer.
Hi! Maybe someone was checking Fosi Audio V3 vs Loxjie A40?
I couldn't resist adding the Sparkos and a beefier (more current capable) 48V power supply, and, well, that little bastard is going to stay.
I even may have plans to replace the binding posts and some internal wiring. It's a hobby ;-)
Fos v3 a bargain? that was yesterday......the Aiyima A07 MAX is the real bargain!😛
Please compare ZA3 to PA7 plus !!
Because I am contemplating upgrading from A08 pro to 2 za3 in mono, or PA7 plus. And upgrading my T8 Aiyima DAC to SU 9 pro. Speakers are Sony cs5
I will get ZA3 and then I can compare them. At the moment I can only say that PA7 plus is noticeably cleaner and has deeper soundstage than V3.
@@JayBeezy31upgrade your speakers first
I would suspect it sounds like trash..yet everyone seems to dig it. I'd love to give it a listen some time
It doesn't. They do. Yes you should.
@@Douglas_Blake_579Yeah, I would really like to hear it. I want to be impressed. In general terms I feel stereo gear is overpriced. If this amp is as good as been mentioned I feel that is a truly great accomplishment. Which value minded people reap the benefits of.

Most online vendors have a 30 day return policy... so the only thing stopping you is that initial cash outlay. If you are impressed, YAY! If not, just send it back.
I use a number of different TPA3255 based amplifiers in a "soundbar killer" system I sell to friends and friends of friends. I will say that I am genuinely impressed by their performance and I'm pretty fussy about sound quality.
The chip itself was developed by TI for pro-audio applications in sound reinforcement and studio monitors. You will also find them in high end AVR systems and even mid-to-high end stereo systems.
Take the leap ... answer your own questions!
I strongly suspect the build quality and durability of these chinese amp. Just at 250 one can get denon m41 or yamaha 202. Also this v3 has no bluetooth and low power.
5Ax48V=240W , 5Ax32V=160W
My a07 sounds better
I have the a08 pro and I agree
Never heard the V3, but a day after getting the Fosi Audio ZA3, I gave my A07 to a friend and sent an AO200 MKII back. Obviously a lot depends on how you use it and speaker pairings, etc., but doing the closest I could to an a/b comparison, I thought the ZA3 absolutely smoked the other two. Might give it a listen if you have a chance.
I upgraded the op amps on the a07 max, first to sparkos then the muse02. The sparkos sounded too analytical in my system. The muse are wonderful sounding. I've ordered the za3 so I can get a complete 2.1 system. Plan to try the muse and sparkos op amps as well.
