hissing noise distance?

How close should I be to my speakers before I am able to hear a hissing noise(receiver on, nothing playing)? From what I understand, that's something you just have to deal with.


I have these set of speakers:

And previously had these:

And I swear I can hear the hissing in the CV system at about 2x the distance as the DCM's. About 3-4 inches for the DCM, about half a foot for the CV sats. At first I think it was the sub-standard sensitivity(I don't care really, they're sats, don't require much juice anyway), but the center channel is the same.


It's not something that really bothers me. I didn't even notice my DCM's made a hissing until I heard on the CV sats. I know I shouldn't be able to hear the hissing from where I am sitting, the sats are all at least 2 ft away, but my room is very noisy. High speed fan on my cpu, 4 other fans going in the case, and an air filter. So even if I can't here the sats' hissing, my mind makes me think it's there, know what I mean?


It would put me at ease if this was just a normal operation and nothing I could about it.


I have a Sony STR485(really ******) receiver, but the hissing distance was the same when I tried them on an HK DPR 1001.


Thanks
