You may be hearing tape hiss coming from the master tapes used at the recording sessions. This sound will be exacerbated by audio systems with an upper mid- range emphasis. When i look at your components my first reaction would be to expiriment with your CDP, try heavier guage speaker wire (i.e. 10 guage generic 100% copper twisted wire)and or try changing the direction your speakers are pointing (perhaps you are listening to them on axis - most speakers sound better off axis). I try these things in reverse order, cheaper that way.
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?

Acoustic Research AR1 (AR's flagship speaker)

Wires are simple 14 gauge from Radio Shack (I can't fit thick wires underneath my rug)
