Hello everybody, first of all, let me introduce myself to this forum, since this is my first post. First post yes, but not first read since I've been following many of the threads you guys have been discussing around. Lot's of info for the neophite like me, who'e starting in this fascinating (and manifestly expensive) world. Well, let me expose my query.I've recently purchased one Marantz SR6200 which, to my ears, works pretty well for Ht as well as music. SOund is nice and warm and I like it very much. However, I've noticed that maxing the volume I can clearly hear noise and hiss from my speakers in stereo mode. I know this has been largely discussed in many threads here, mostly devoted to the SR7200, but one think that I can't figure out is up to what point noise and hiss is normal, and starting from what level is unacceptable. So let me expose what I find by hearing to the CD analog channel without playing any CD: 0 db's: you can't hardly hear the hiss. Only sticking the ear to the mains I hear a soft noise. +5 db's: I must put my ear to the speaker to hear a hiss, but once I do that I hear it without doubt. +10db's: hiss is clearly there. I can even hear it (though very low) from my sitting position, 10 feet away from the mains. +15 db's: I clearly hear the hiss at the speaker and at my sitting position. Notice that +15 db's is the max volume this unit can reach, so I understand 8at some point) that hearing noise at that level is more or less normal. Furthermore, all this happens only at the analog channels. Digital ones are hiss and noise free. Another interesting thing is that the level of hissing depends on the source selected: low for CD and DVD, more apparent for TV and VCR... is that normal also? And the last thing which I do believe is not normal, is the fact that appart from the hiss, I hear sort of an intereference signal when I connect a COAX cable from my DVD to the receiver. If I disconnect the coax from the DVD but keep it connected to the receiver, the noise is still there. I must explicitely disconnect it from the receiver to stop the noise... but the nice thing is that the noise can be heard only in analog mode (while the coax is digital). So what's going on? I presumme this sort of intereference shouldn't be there, isn't it? Well, i guess that's enough for a first post. Help about all this will be certainly appreciated. Cheers, Ferran.
