About this deal

The future of audio looks bright for consumers as these new generations of Class D amplifiers (the A07 uses the Texas Instruments TPA 3255) are inexpensive (compared to quality tube amps and proper class A) and truly sound great. It's worth noting that this setup isn't perfect because the Aiyima A07 came with a 36V 6A DC adapter, while the BT20A Pro had a 32V 5A adapter. They say it has a very rounded sound, is fantastic sounding budget amp, and is clearer on vocals than some of the expensive behemoth amps. To give you a little tip, if turning the Bass knob all the way to the right, I am able to listen to KLH Model Five without even employing the Adam T10S Subwoofer at all, the sound has super heavy bottom end, and the AMP itself adds a lot of weight and substance, but also bass, and even sub bass to the speakers. I think the wider design on the MAX allows allot more space at the back of the Ampflifier - meaning cables are well separated - see photo below.

Lastly, concerning the DC input, both amplifiers can handle a voltage range of 24V to 48V, allowing you to use a compatible adapter within this range depending on how much juice you need for your setup. Such is the case for users who pair the unit with a Fosi M-03 or an Aiyima A3001 sub amp to power passive subs or control active subs.The OP amp is powered by a ±12V dual power supply, and the performance of the op amp will be more fully utilized, with better dynamics, and more details at the same time.

But no matter what settings I choose for the other amps, when I switch to the A07, which only has on/off, it sounds better to my ears. Additionally, the volume-controlled pre-out on the BT20A Pro is a valuable feature for multi-zone audio setups. But recently one of their competitors (Fosi Audio) went "back to basics" with their design for the Fosi Audio V3 - not adding "features" but using higher quality components, a new orientation of the amplifier board and better cooling to provide a high quality alternative to Aiyima TPA3255 products.
