    At all the naysayers whose bias is showing, these perform very well and sound great. Disruptive because of the price point and viral marketing and direct shipping which may be uncomfortable for traditionalists.
    I’ve replaced nCore amplification with a pair of these and they sound just fine. Levinsons new company Daniel Hertz is using nCore amplification in their new amps selling at mega bucks. For the modest price the V3 mono is surely a great audio bargain despite lacking the cachet of other brands.

    I did several tests with amplifiers with TPA3255. My intention is to use my tubes in the cold months and use digital amplification in the warm months. In addition to being environmentally friendly, you also save on your electricity bill. The best I achieved with digital was using a tube preamp and very well built power supplies (this is essential). In this way, an extremely natural sound is achieved, which only loses a little to the valves. I did a blind test with some friends and most of them couldn't identify whether it was the digital amplifier or the one with tubes playing.

      If you optimize everything except the amp you will achieve a result that might be difficult for a untrained ear to notice or pickup. Speakers will be extremely important as well. But soundstage, dept, low end, mid and all is restrained compared to better gear. Great value for the money without a doubt, but please be realistic... It's getting dumb at this point now. P3 is a horrible pre btw. Kills soundstage, it's not sounding clean and clear. Yeah I upgraded tubes, op amps and that was a waste of money for the minor differences experienced. Near field computer setups and similar they are amazing for thou

    A lot of people dissing these Fosi amps. It's easy to speculate but from personal experience I think the ZA3 is not only good for the money but can definitely compete with much more expensive established brands/models. I'd be curious to hear how the V3 monos ACTUALLY sound against the Schiit Aegir monoblocs or other integrated amps in the $2000-3000 range. There's another RUclipsr who felt the ZA3 wasn't shamed against a $5000 Naim Supernait 3 in an A/B sound demo. Opinions are all over the place on these.

Since I do have the first V3, 2 mono V3's, I have the P3, the bt 20 pro, I have tested Tangent products pre and power ampster 2(that at least give the promised power rating), better base and overall better sound picture). I've used a great Hypex amp in the Buchardt I150 ++. It sounds very good on its own and also used as a pre with the V3, Galion A75, class A amps, Tubes.. All tested on the same speakers that I know very well .
      That you in your little delusional world believes it matches or even comes close to better gear is on you.
      Even if the stereo V3 was a massive disappointment, I had to try the mono V3 to see if it came close to the review hype. It does NOT. It is a great little nearfield amp thou.

    If you want to get the most out of them you can get a 48v 10a (instead of 5a) for each of them. I think the limitation is in the power supply capacitance. You will be driving them even hotter though.
