This amp made my Pioneer SP-BS22-LR sound amazing. Give it a try if you have a 2.0 system. Amazon has easy returns. I moved up to the BT30D Pro to power my passive 12" Infinity Beta subwoofer. I'm amazed at the power and sound quality of both of these little amps.

    This is a great little amp per Randy The Cheap Audio Guy, whom I trust. It's got a TI chip. I've seen it around this price with a coupon, but I've never seen it for less and it's usually more. I got the AIYIMO A07 instead which has the same chip and sounds great.

    Any reason you chose the A07 over the BT10D? I really like having bass and treble controls and my speakers sound so much better adjusted.

    I'm switching to the BT30D Pro because I want to power a powered sub as well. I hope they sound as good or better as this TB10D. Same chip.

    The A07 Pro would be more akin to this than the A07.

    Stacked my A07 with the AIYIMA DAC A2 which has treble and bass knobs. Also the A07 has a 3.5 out that gives me the option of powering a subwoofer, the Fosi doesn't have that.

    How would you compare the A2 to a Schiit Modi+?

    Don't know if mine was defective; purchased bt30d and it sounds decent at low volume... Lower than a normal conversation reasonably loud it sounds like garbage and it can't get small room filling at max volume. A $200 Sony recieve is louder at less than 1/3 volume as bt30d is at max distorted garbage volume.

    Interesting. BT30D is 165Wx2 + 350W and TB10D is 350Wx2, so the mains will definitely get less power. Hopefully my speakers are sensitive enough to sound good with the BT30D. Another option is to upgrade the power supply for the BT30D to a 36V 10A to give it more power. It comes with a 32V 5A.

    With the included power supply brick, real world tests are closer to 25 watts to 40 watts x 2 channels, 8 ohms, 40-20,000Hz, at 1% THD. And even then, these will overheat if pushed too long. You're always better off with an older receiver. You just give up the small form factor. Find some very efficient 8 ohm speakers and don't expect party level output for hours, and you'll be fine. You can purchase a larger power supply brick and get more power, but you need to keep the unit cool.
