So, as some of you advised me, I have used ceramic capacitor for signal input (instead of plastic ones) and now it works well !
I have read for a last time carefully the datasheet, and there is no mention about a specific material for the input capacitors, so I am a bit angry against Philips.
Anyway, I have made listening tests on good reference speaker, and although this is not hifi purpose, the quality is not so bad at low-mid volume.
If found there is a bit too much noise when no signal, do you know how I can reduce this background noise ? (this is not hum, but broadband background noise)
