The left channel hisses and crackles during more refined recordings ( Jan Garbarek ) with the volume above -10. I tried everything : exchanging cables, cd players, cinch cables and the problem seems to be analog inputs !!! Even tried to hook up the cd to another input.Same result. With CD player hooked with optical cable, everything works fine !!! And,it's not the speakers, because it does the same thing with the headphones out. I still don't know what to do...Maybe it's the preamp section ??? Should I return it ???? Tin I'm using B&W CDM 1 SE front speakers.
