Fosi Audio BT20A Pro

I use a 48v power supply and Polk Audio Signature S15, the sound quality is actually much better than expected and it is very successful in high resolution audio files via wireless connection, thank you Fosi family.

Using the 48v power supply with the SparkoS Labs Op Chips. Surprisingly good audio definition and sound stage. Clean output. Definitely recommend!

Fozi bt-20a pro

Volume knob is loose right out of the box, after a few songs it cuts power output by half roughly, I have tried my Pioneer receiver when it does this to make sure it's not a wiring issue and not the Fozi amp, it makes no difference if wired with RCA cords or Bluetooth, I like the compact size and weight of the Fozi but it's performance after 3/4 songs is poor, it's not getting real hot or anything weird, i tried a fan and makes no difference, I run the amp with a eq and Cerwin Vega at-8 speakers, it makes good music at half volume for a few songs and before you know it, it's turned up all the way and only puts out about half the power. I checked power supply and that's working fine, I won't beat your products up on line, that does no good and Fozi treated me good, I really appreciate the 20% discount and like the amp, just want a amp that can play loud for a couple hours. Thank you Fozi Audio!!

Nice little amp for the money

I am using this amp in my garage with Infinity IL10 bookshelf speakers with the blue tooth connection and have about 100 hours on it. The sound is super clean, a little on the bright side I would say. The tone controls are an excellent feature. What can I say its definitely a keeper and its staying in my garage. It would also be great to use for a mini stereo or computer set up. I don't know if its actually 300 watts worth of sound cause my speakers are only 8ohms. You would need lower impedance speakers to get the full power from the amp.
Also I ordered the upgraded power supply.
