Just got an email this morning with an ad for an "early bird" sale (30% off) on an upgraded version of the original Aiyima A04 amplifier:


Since I don't own the original A04 (I got the D03 and the T9 Pro), can you tell me what improvements the company made, and whether it would make sense to test one as an alternative to the Fosi Audio BTA20A Pro?

Hello,
Has anyone used the updated A04 yet? I'm deciding between updated A04 and A07 pro. I plan to use it with 2 Bose 101 4ohm 60w speakers and 1 subwoofer, which one suits me better?

I bought one and it seems fine to me. For $60 +/- , it’s hard to go wrong.

Received the upgraded A04 and it really sounds on same level (both using 36V6A) as the upgraded A06, which I really liked at the $52 price. They use different chips but both rated at 170W per channel so makes sense. I like the case on the the A06 better, mostly because it has gnurled knobs and the A04 has smooth knobs like Fosi TB10D. A04 might be a tad warmer in sound just a bit. A04 case is 1.25" longer than A06. Both sound better imo than stock A07, which lacks bass for my listening.
