They definitely have the ability to make high quality amps. The v3 mono amp in particular has measured really well according to Audio Science Review. I haven't found a lot of information on the T20X out there (lots of MKII and lots of T20 without the X) but the few reviews I saw on the T20X seem decent enough. Not 100% sure what the tubes are doing in the signal path given that this is a TPA 3221 amp, but the price is so good I went ahead and pulled the trigger (thanks OP). I had a Topping Mini 300 in my Amazon cart that I was planning on ordering in a few days but this deal is a no-brainer IMO.

Have this and powers some akgs. Great price. Not sure if tubes are as effective as dedicated tube amps but definitely has removed the fatigue from K7XX and K702 headphones.

AliExpress will change the prices in hours and sometimes within minutes or when you click on checkout.

This is a DAC? Will this take away static interference noise from my 2.1 setup on my PC??! I currently use a static filter addon to prevent it but it reduces the sound quality
