Hi Als
Liked your video, especially the unboxing and I really liked the sound the Fosi TB10D Amplifier made when the treble and bass controls were set at 12 o'clock. However, I do have one small criticism, the instrumental music you sampled did not have enough instuments in it to test the amplifier, i.e more mid-range sounding instruments. I also thought the music was a bit bass-light and so the amp's bass reproduction was not really tested.
Bearing in mind that I am listening via my TV speakers, after the sound has been processed through YouTube, so my initial assessment could be wrong, nevertheless you have produced another very good video.

Can I use it with my 6 ohm 60watt speaker with heavy magnet around its woofer, I mean my speakers are heavy. I was wondering if these new generation amps can play them like conventional old school of 90's OR 80's.

⁠plz help I bought a Fosi BT20A pro amp and I’m trying to figure out the best way to connect my source wich is my iPhone 15 and my MacBook Air as well. I have a rca to aux cable that I use to connect the fosi amp to my iPhone 15 with the usb c to aux dongle. Would the shcitt dac be any better than the dac in the apple usb c to aux dongle??? I noticed that the Bluetooth volume on the fosi amp is louder than the rca to aux cable method. Would the external dac be louder than the usb c to aux dac??? I also use Apple Music lossless.
