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.

Take deep breaths and quickly click close page and move onto something else before you rationalize getting more.

And remember that you deserve a little treat now and then and find a way to justify buying it.

"Someday" you can sell or give away some stuff you don't use anymore.

Buy it. It's small enough to hide anywhere and cheap enough to not be a big risk. I like this type of amp so much I have an extra one in the box just in case I feel the need to deploy another one somewhere. I currently have one for my living room, my shower, my kitchen. my patio, my dining room, and my garage. If you have anyplace in your life without music you clearly need one of these.

Quote from Jason27104 :
I find it hard to believe that anyone with any sense uses this with 3k speakers. 1% THD is moderately bad. You should really have below 0.7% for anything critical. 10% is straight up terrible. You could take this money, spend it at goodwill and walk out with a receiver that is literally 10x better in terms of distortion and several times better in terms of stereo wattage. This is mediocre for a desktop amp, much less living room.
No one really listens at full 300 watts unless you are almost deaf so 10%THD is at full 300watts seems just right. Yes, it is high, but what do you expect for a $60 amp? THD increases as you turn the volume up.

I was replying to people talking about this $60 amp being suitable for people with ~$3k speaker budgets and how that is laughable bc the THD is astronomical if you use even a third of those 300 watts. If you spend 3k on speakers, you aren't going with a $60 dollar Fosi chi-fi amp unless both of those things were in the same box from goodwill. A guy posted his self case study of one to confirm. I exaggerate to jest, but not by much.

OMG, are you my twin? Boxes of perfectly good impulse purchases I can't let go of, and can't be bothered to put out for a yard sale (or eBay)…
