Some time ago I ripped all my cd's to mp3 at 128 Kbps so I can play them without my cd-player.\nI stream them by VLC to my stereo , with a cable.\n\nNow when I turn up the volume and listen to, say Andrea Bocelli, the sound has a disturbing crackling or sizzeling around it.\nThe stereo is rather old, so I took my even older Pioneer sx8500 from the storage, and used it to play.\n\nThe sound was a little better for sure !. but even then ther was some distortion in it.\n\nWhen I listen by headphone, still the same. So I doubt if the amplifier is the problem here, althoug it has influence on the sound.\n\nFor years now I am using linux, so I used it also to rip my music...\n\nBefore buying a new stereoset, I was thinking of the Panasonic SC-PMX70B, which has also a DAB tuner, for what it is worth, but at least you have one then. Internet in the reciever is not realy wanted, because you also need some app then to navigate. I still use some PC for that job. Yes also linux.\n\nDoes anybody has encounter such problems also? and what can be the source of those problems.\n\nCould it even be the age of the speakers ? now around 22 years ( visaton selbtsbau ) which were always very good.\nWhen for example listen to some internet station with organ music, say "the orgen experiance" I have nothing to complain.\nAlso piano music sounds wonderfull, realy, no joke!\n\nSo I am a bit puzzled why voices sound bad when the volume gets up ...\n\nBut voice is something total different then organ music.\n\nAny help or explanation or link to some answer is very welcome.\n\nEDIT: to shortcut some discussion.. It is not a problem with cables, connection and so. It is about the music or codes or ?
