I think the first response hit the nail right on the head. I would guess tape hiss on the master recording. I noticed it on some albums I have also. Very annoying because once you hear it, you'll notice it more and more everytime. I guess I don't know how to redcue it, but getting rid of some of the mid range emphasis certainly may help.
Hissing
When I play albums such as Rolling Stones 40 Licks or any Zeppelin album I hear a constant hiss in the background. The louder my system is, the more apparent the sound becomes. However, on other albums, this hiss is non-existent. I've heard that this is related to the way the album is recorded, but I have heard the sound reproduced much cleaner on other systems. What can I do to reduce this?
