"I knwo that I should ( and AM in the process of)addressing the room itself carpet is in order and some accoustic paneling to kill the early reflections,should I do this first?"
You've got the acoustics of a grade-school cafeteria --linoleum floors? To answer your question--YES. Go buy some very good acoustic treatments, foam will be fine, a nice Turkish rug for the floors would look great if you want some styling, otherwise just get any carpet in there. I would straight to Istanbul to get the best prices for the Turkish rugs. Get back to us once that's done.
"I have changed the tubes in the CDP as well as the PreAmps
the Jps labs provides me with the transparency speed and extended Hi frequencies,,and resolution, but with noticable
sibilance could it be the Ac line conditioning or lack of it that is introducing the stridency and graininess to the sound? if so where can I start?
What brand power cables offfer the best shielding or get's the GRUNGE out?"
The room is probably so bad--I don't see how you could even hear if those are really your problems.
Speaker/room interaction is still the most important. Hit the sidewall first reflection points first, the center wall between the speakers, and then the wall behind the listener. Search previous threads on room acoustics and maybe get a good book on the subject "Audio Cyclopedia" or "The Master Handbook of Acoustics."
