Greg, you're great at recording and presenting us sound demos. Your Qualio IQ are fantastic speakers, and the T&A dac is excellent. I know you're trying to expose the Qualio brand to a world wide audience and using the latest China cheap amps brings eyeballs to your channel. But for those of us who might purchase your speakers, it's essential that we have demos with high-end amps. In my case hearing the QUALIO IQ with the Hegel h390 or Michi x5 integrated would be fantastic. Thank you for your excellent work.
This little amps are highend (Power without the price)! The Qualio sounds awesome on Class D amps they will also better sounds by better amps like the Dartzeel CTH-8550 (45.000$ or 50 kg amp called ASR Emitter I (15000 $) is but the price...? 110 kg amp Emitter II 20.000$). I use actualy the Fosi Audio BT20A PRO with MuseS02 and it sounds great - i fell in love with this 100$ amp. ❤
You are wrong. I have several amps, a 300B and a Gato Amp150 and built speakers very similar to Qualio (fullrange +AMT + simple but high end filter, powered subs). I am using Fosi ZA3's with Sparkos opamps because of Gregorsz's review. And my pair of A70 mono's is incoming from pre-order. These small amps are really, really good. And they don't use much electricity. They sound great from my Laiv dac and my turntable setup which is even better.
Great review I just bought a couple and replaced my Z threes that were mono blocked and I can’t believe it. This thing makes me cry how beautiful the music is.
Hi Greg, saw this video, and straight away I placed order even before watching your full video, because I have full confidence in you. I was very hesitant to purchase the Fosi V3 monos, but decided to give it a go. How correct you are, and now my high end amplifiers are gathering dust🙂 thanks for the tip. I hope the Aiyima A70 cold do better than the Fosi V3 monos. Can’t wait for it to arrive, will keep you posted on the comparison. Thanks keep up the good work.
I just installed them but not with Sparkos yet. First listen: good sense of space. A bit thin and shallow (NE5532 opamps!). I can't tell the effect of PFFB yet. Very clean and fast. Need to turn up the preamp a lot higher. Finish is very good. The PS bricks are GaN technology and a lot smaller. The auto off is very nice. The sub-out does not follow the volume knob. The sub-out frequency LP is not very useful IMHO. It should have been a HighPass for the main. The left front
Try to make a comparison with the IRS2092 monos, they are cheap, have a lot of power and are superior in terms of quality to the Fosi. Amazing how they have remained so hidden until now.
i'm really interested and impatiently waiting to see you presenting the QUALIO Amp !!!!. when will it come out ???. i can't wait to see it pairing with your gorgeous QUALIO-IQ ULTRA !.. thanks for your demo.
Wonderfully recorded! I was able to tell apart Amp A & Amp B from the beginning and indeed using mono configuration on XLR and hopefully soon op amps rolled will reap immense improvement & pleasure in your listening! Should I upgrade my Fosi ZA3 monos in your opinion?
Thanks for the great demo. I didn’t finish to find which is which. The difference is minimal if any to me. I think A07 max runs too hot. Hope the new model has better thermal performance. Other features such as trigger etc would make the whole amp easier to use.
I love your videos and really appreciate your work. Thank you for that ! Can I also improve the sound of the AIYIMA A70 Mono with the Sparkos Labs SS3602 ? I hope for your answer. Dieter from Germany; thank You.
Hello, are these monoblocks better than chinese clones like the Dartzeel D5pro for example? I have a pair of Fyne audio f501 speakers with a Hegel h95 amp right now in my system. Would these monoblocks improve the sound quality over my Hegel h95? I love to roll opamps and tubes also if that makes sense 😊 I already have a little dot 1+ with very good tubes as preamp, so love it.
There is an error in your description from copy pasting from the Fosi dac... What i could hear, they are both with the standard opamps? I assume you don't have a box of extra Sparkos opamps. I thought it sounds a bit thin. And why do you already have them? I pre-ordered them!🤨 Edit: I just got them. Playing now. I thought they would have a high pass filter for small speakers but it seems I was mistaken. Also, I later learned the subout is not controlled by the volume knob like the Fosi. So please, more details! Edit: as they are playing now I noticed I need to turn up my preamp a lot higher than with the Fosi ZA3's. Not really problematic but noticable. Love your work!
Useless, Amp B is around 1 dB less loud on the tracks (Peak RMS measured), so any comparison with not very exact same loudness is fooling you. Sorry to say that. Otherwise: Thanks!
Yeah, I never listen to that one. Yuck. I only listen to the jazz tracks-“I am better off” (for vocals) and “Folium”-sax & piano, I just like that piece…

VS V3 pls
VS V3
Great review I just bought a couple and replaced my Z threes that were mono blocked and I can’t believe it. This thing makes me cry how beautiful the music is.
Greg-I just ordered the Fosi V3 monos with separate 48v 5A power supplies (not arrived yet). I hope the Aiyima aren’t better!
Fosi Za3 mono blocked going in the box to sale.
The detail,soundstage
Breathtaking

I wanna hear your take too and my Fosi V3 monos haven’t even arrived yet!
Great test. There are many new amps. I shall be waiting for a group test .......!!!!!!!
I preferred AMP B. Thank You.
It's a pleasure to watch your videos, thank you very much. To my ears A sounds a bit bright and less bass, I like version B better
The new Mono sounded more open and refined. Liked it better. But too many controls on it for a Mono block.
Aiyima A70 stereo vs. A70 Monoblocks vs. Fosi ZA3 Monoblocks. Waiting for that..

Excelent sound as always...A-B no diference for me..never the less my good equipement.
Regards...
P.S. just keep on as usual!
i'm really interested and impatiently waiting to see you presenting the QUALIO Amp !!!!.

Why didn't you compare 2 x a07 max mono and 2 x a70 mono??
Thanks for the great demo. I didn’t finish to find which is which. The difference is minimal if any to me. I think A07 max runs too hot. Hope the new model has better thermal performance. Other features such as trigger etc would make the whole amp easier to use.

Can I also improve the sound of the AIYIMA A70 Mono with the Sparkos Labs SS3602 ?

Virtual Hifi Hypersonic opamp is the answer
hi, this A-B test was easy 😉
pretty cool shirt 👍🏻

Do a comparison with Accuphase E-5000 🤭
Have you tested the amp with different power supplies, between the 48v 5amp and the 48v 10amp?
There is an error in your description from copy pasting from the Fosi dac...

Love your work!
Which is the best between Ayima a70 mono and the Fosi V3 mono with Muses02 opamps?
its been 2 weeks, i imagine comparison vid coming soon ? hopefully before amazon prime day ends ...lol
When does it end ? I plan to release the video on Friday ;)
@@VirtualHiFi I know right endless dacs and amps opamps 😱.
Ok great, for today I just need a hint 😉😉.
See you Friday.
Sure, "A" sounded way better. Thanks. I left my comment for A07 "boom box" in another your video sir. No changes
Please compare
Fosi V3 Mono vs Aiyima A70 Mono
What is AMP A and B
Are there replaceable opamps in the a70 mono?
I researched the amp and found out that you can replace the op amps.
Have you tried op amp rolling with the a70 mono?
Which os better Fosi V3 monoblocks vs A70?
I bought 2 A70 mono build a 2.1 , aiyima /trustworthy
😳😳😳😳😳 You need to see the vídeo called Aiyima Mono from Scientific Audiophile. 😂😂😂😂😂
To niema końca...😅
Useless, Amp B is around 1 dB less loud on the tracks (Peak RMS measured), so any comparison with not very exact same loudness is fooling you. Sorry to say that. Otherwise: Thanks!
that first song is a pure garbage
Yeah, I never listen to that one. Yuck. I only listen to the jazz tracks-“I am better off” (for vocals) and “Folium”-sax & piano, I just like that piece…
Which one is better, Fosi V3 mono or Ayima A70 mono?
Only you can decide that
Be VERY VERY careful bro
Digital amps will screw ur speakers
Digital amps are like Power inverters , just like 12v DC to 220v AC
Thats my opinion
Nonsense…
