Really enjoyed the review. I liked how you added more elements like the measurements part. It gives an overall better way to understand and relate to the subjective part. I've red somewhere fosi are releasing a stereo unit next and also a preamp of some sort. Keep up the good work!
I was waiting for this review, thank you so much! Whatever one may think about Fosi, they do a great job listening to their customers, critics and suggestions. I'm running 2 ZA3's in mono now and it's tempting to switch to these, especially re. the upgraded 48V 10A psu's. I guess we have to wait a bit for further measurements re. powerspecs, but they surely upped their game. Cheers MAD! 👊
I was wondering what it would do with two power supplies. Everyone who has reviewed it is happy that it works so well that it feels like a game changer. Great review.
I have the ZA3 in dual mono setup that I'm happy with. Do you think it's worth upgrading to the V3 mono? I've fitted Sparkos opamps to my ZA3s, but these mono blocks need 2 opamps per unit as opposed to one each for rhe ZA3. Could get expensive!
Hi, i just this week received a douk pro 7. I could compare it with my class D T+A Cala. The douk came with a 32v power supply. I found that it was slightly subdued in the mid range then the T+A. I replaced the power supply to 48v, wow, what a difference! It sounds slightly brighter on the high frequency, then the T+A. The imaging, instrument separation is very good. My speakers are Castle Knight 4's, which are on the warm side. I tried a lot of different music, from Jazz, Houston Person is very good, to rock, pink floyd The Endless River, the organ was awesome, to Heilung. The girls voices are beautiful. The power supply made a lot of difference. I heard the combined power supply to those mono blocks, caused noise. When he changed it to separate supplies it produced no noise.
I never had any noise problems so no idea, but yes I heard that some units were coming with this problem and that they add an filter to the power supply!
As I said in the review is hard to defined warmer cause the ZA3 has load dependency problems that will let them sound different between speakers, and warmer where? Bass mid or treble? Btw no I didn’t find it warmer at all, where the V3 mono i will describe it as open and extended with a vivid mid presentation and full of air top without being never fatigue or aggressive! With some speaker ZA3 sounds brighter actually, so definitely not warmer. Hope this helps!
I have za3 running mono with sparko.s opamp paired with klipsch speaker and tube dac. Comparing to my tube integrated, the za3 has richer midrange and more detail; however, the tube has more open sound stage and less pint point for instruments.
I’m ordering the amps but with regard to power supplies, I’m torn between going for two of the 5A’s rather than one of the 10A (with the dual cables), two questions: will there be any differences in speaker output power from the 5A and 10A and will this affect sound quality? I’ve heard that if you use the 5A’s then the amps deliver less power, is this true?
Thank you. They’re offering two options through kickstarter and I just wonder why? I love your review and that’s what made me confident to buy the units and see how I get in. Thank you so much.
I agree with the sounding slow. I returned my mc100. I was tempted to order these but after going back to my Rotel it’s so much more musical. They are good for the money but they are over hyped. A Rotel A10 sounds much better to my ears.
@@DavidBurns-sq4kd i will probably not generalise too much on AB vs D, there are amazing Class D out there but are expensive, what Fosi Audio accomplished with V3 Mono is IMO a bargain, great quality for the money, impossible to achieve such power and transparency on class AB in this price range!
To be honest I didn’t test it cause i know very well my LRS+ , once I powered them with the SPL 1000 mono amp (750W in 4 ohm) to let them shine! Even my MC312 is struggling with them so..
@@MadAudiofficial yeah the LRS+ are a power hungry beasts. BTW I think you should give it a try... if it works the LRS+Fosi could be a killer budget combo!
Help me here plz. I just wonder why they made or lauched it just after releasing the Z3. The Z3 was working fine as a mono unit. I am one of them who bought 2 ZA3's after getting impressed with reviews like this on youtube, and now finding it difficult to cope after learning that these mono units came out from Fosi. Should I feel bad?
Absolutely not, ZA3 is a great product, just need a more careful matching when is come to choose the speaker, just that! Enjoy it and take a look for a possible op amp upgrade in the future..
@@bhaskarsaikia5586 as I said in the review speaker matching is the key with ZA3, V3 mono sounds less in your face and more neutral, but again depending what you are pairing with!
@@MadAudiofficial friend you just don't know how bad I feel about this really. I bought a pair of ZA3's only last month. Now I am sure I won't be able to love them too much as you had more nicer things to say about the newest Fosi V3 monos🥺.
@@bhaskarsaikia5586 you don’t have too! ZA3 is a different product, V3 is just a power amp where ZA3 you can control also speakers unbalance! Be happy with them if they sound good with your speakers and one day as i said you can still upgrade op amp or sell them and test V3 mono or similar. Audio is like that, there will be always new products that are Promising better results and technology..ZA3 is fantastic for the money!
To be honest I didn’t test it cause i know very well my LRS+ , once I powered them with the SPL 1000 mono amp (750W in 4 ohm) to let them shine! Even my MC312 is struggling with them so.. really u want to drive magnepan with them? I mean i cam try but i am already sure they will not be able to do it!
@@MadAudiofficial I have tried a single Fosi ZA3 on my LRS+ and its fine, but I listen at medium volumes. Perhaps it depends on what you mean by "driving it" successfully. I do prefer the sound of my obviously more powerful sounding 150wpc @4ohm class AB amp, but I always think that class D sound is wimpy and lacks body.
@@geevee1045 drive a speaker properly is for me bring out at least a good sound stage with a proper imaging free of artifacts, must sound free, full of life and not constrained, doesn’t matter if at moderate volume level. Drive a speaker is sometimes misunderstood with make sound coming out from them, IMO.
@@MadAudiofficial Yes, I agree. I've always thought that people are too focused on how loud an amplifier can play, instead of judging the sound quality. I do prefer my 200wpc @4 ohm class AB amp on my Magnepans vs class D. My class AB amp has a bigger sound stage, more powerful bass, piano has weight, and is the sound is more beautiful and soulfull.
Not really since I performed all measures with less than 1V, you should have the amplifier clipping above 1.2V if i am not wrong, btw Fosi should add input sensitivity specs to the products page!
@@MadAudiofficial Amplifier will not clip (maybe closer to 2 volts it might) but the difference will be in frequency response. ZA3 sound very very good, in fact sounds better than all my other amplifier, most expensive is 10K Euro...bought v3 mono, too and I'm selling the old ones but the ZA3's.
@@MadAudiofficial absolutely and the price of the "really good stuff" was more accesible too!! People like you and me could afford top hi-fi gear in the 80s. I was a teenager and I remember perfectly the prices... top of the line "end game" speakers from B&W, KEF, ecc were $2k or $3k at most (that was a ton of money back then, but any person with a good job could afford them like my father did back in the day and he was an employee not a millionaire). Now with $2 or $3k you can't even get the entry level offerings from those brands!! You have to spend $50k, $100k to get top B&W speakers and if you want matching japanese electronics like Accuphase you have to add another $30k or $50k easily. Those prices are totally out of reach of even the best paid professionals!! I can't even dream about them and I'm a well paid engineer!! That's not normal, this industry is not normal. I think the hi-fi industry is totally sick and that's why China is taking over it with down to earth prices and excellent products. I hope brands like Fosi the best, this industry needs a revolution.
I will not call it unnatural cause is not, but some instruments like violin or cello lack a little bit of nuance and realism, specially on ZA3, moving to V3 Mono is another story but still not at the level of a good Class AB amplifier IMO! BTW for price is more than excellent.
It's maybe a good amp, but doesn't worth its price. Buying a TPA3255 amp with $140 is insane. TPA3255 module only worth $15. Then the case worths over $100? What so called PFFB is just a few caps and resistors suggested in the TI datasheet.
What if i tell you that could cost double of the price and still being a great value for money amp? Please test it and send it back if you don’t like it, just let me know what you think about it! No hype, they did a fantastic job!
@MadAudiofficial It may be a great product, and I have respect for their line and wanted to know more about this one, but I can't take to serios this titles and reviewers anymore! That's just me .

I really would love to see an integrated amplifier under 500$ from Fosi Audio!!!
I was wondering what it would do with two power supplies. Everyone who has reviewed it is happy that it works so well that it feels like a game changer. Great review.
Thank you 🙏🏽
Two separate power supply is more reasonable I believe.
Nice, pretty thorough intro review. I am thinking they might get hot with the new 48V 10A PSU. Wondering whether two 48V 5A would keep them cooler.
Thx, I keep them under test for hours without problems so i think is fine, just need to let them breathe and not closer.
You need 42v 8A and it would be great 👍

If you are happy with ZA3 sound keep them!!! No reason to change, ZA3 is a great product, just need the right speaker👍🏽
thanks for our review. Where the v3 mono can be purchased?
Check the kickstarter link in description please👍🏽
Do you think the V3 mono cannot compete with the Musical Fidelity A1 regarding tone timbre?
Power yes, Musicality absolutely not! A1 is a symphony..
