Quality and sound is great. The unit does get a bit warm.

Bluetooth is always on and broadcasting. There is no security to the Bluetooth so anyone can connect to it and interrupt my listening through the hard wire, which is a big flaw if you have random people or neighbors connecting to the device by accident via bluetooth and there is no way to prevent it

Power of a small miracle.

Fosi Audio BT30D PRO gave life to my pair of KEF q150. Incredible sound, thank you Fosi Audio for the verification that expensive perfumes come in small bottles!

Good. Could be better.

On the plus side, I like the small size and low idle power consumption. The amp sounds fine. No complaints about audio performance but some things could be better:

The manual is poor. Especially, it lacks necessary information about treble and bass settings. Where is the position for no treble boost or bass boost? (fully CCW or 12 o'clock?)

2. The front panel silk screen should be above the controls not below. The silk screen can't be seen below the controls.

3. The silk screening should include markings for bass and treble boost and cut so there's no ambiguity and customers don't have to contact support.

4. The bass and treble controls should have detente positions so users know where no boost and no cut are by feel.

5. The subwoofer channel frequency knob could use some markings to let users know about where the cutoff frequency is. The filter slope is too gradual. The slope should be much steeper.

6. I'm very skeptical of Fosi's cooling solution for the 3255s. I'd feel better if there were holes in the case for air circulation or mounting the 3255s against the case as a heatsink.
