Horrible for quiet music
The sound might be good,
But if you have quiet music, than the amplifiers thinks, he can mute till it is louder again. It isn't fast enough and you can here the unmute.
For example a piano, which plays only a few notes. The attack you will not here. It unmutes to late.
Also if you have a quiet flute at the same time, the flute will be muted.
It is horrible for me.
It does not depend on the input. It does it for analogue and digital input signals.

Pas utilisable à bas volume !
Cet amplificateur marche très bien et le rendu sonore est très correct. Cependant il a un défaut important. A bas volume le son se coupe et il est donc inutilisable pour par exemple pour une utilisation sur un bureau.
Fosi audio ne propose rien pour arranger cela. Dommage...
