In fact the amp is using exactly the same components as the SMSL DA 9. The design is just different.

I'm running in bluetooth right now, just because I don't want to haul too much stuff down here tonight. Connecting was easy/normal w my Samsung phone. Unfortunately this phone doesn't do Aptx HD, so I can't test that. SBC ..............................................................................16bit/44.1 kHz_328kbpsWeight ..........................................................................................3.3kg/7.28lbs I'm running it right now on my "test bench" (aka in the garage) before I move it inside. I'm connected to some Snell K/IIs I keep down here for just such an occasion. Build quality is definitely a step up vs some smaller/cheaper Aiyimas I've been messing with lately. Well, at least fit and finish - I can't comment on the internals.
