Works nicely, BT connected easily to my projector. Sound is crisp, not much perceptible distortion at higher volume. Suits the speakers I have well, need a sturdy 30V 600W+ PSU to get the best out of the amp, especially if you like to drive your bass hard.

Mały, przyjemny w odsłuchu wzmacniacz. Zaletą jest możliwość zasilania z zasilacza od laptopa. Trochę męczą 4 funkcje pod jednym przyciskiem.

Small, pleasant-sounding amplifier. The advantage is the ability to power it from a laptop charger. The 4 functions under one button are a bit tiring.
