Sibilance how do I get rid of it?

Hello
I am currently experincing a problem with sibilance in my system,I must admit I know that unless I set up a overly dampened ( lack of Hi's ) set up, I'm almost always going to have some degree of siblance,I listen to mass produced commercial cd's so I know that this is atleast 40% of my problem , and my listening room 26'x14'x8' is relatively live,,lanolium floors..no dampening,,etc,,
But somewhere in the back of my mind I hear "you need to do careful system matching,
My system consisits of:
Cal Aria MkIII CDP
Conrad Johnson Pv10a Pre
& Conrad Johnson PV 14L Pre
Llano A100 SS Amplifier
Dynaudio Contour 1.3 2 way's "GLORIOUS Midrange and Presence"
JPS Labs superconductor FX Ic's
Tara labs Time and Space with TFA Return speaker cables
Transparent Power Plus Power cord &
MIT run of the mil powercord on the Llano power amp
I have no power conditioning whatsoever except some hospital grade junction boxes in which I have the CDP & Pre's hooked up-AMp straight to the wall.
Now I have experimented with various IC's and speaker cable Discovery,Cardas,Transparent..etc
I don't want to address this problem thru cable choice
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? I've heard good things about coincident
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? then get the ac conditioning? has anyone had any experience with Marigo Powercords, shuyanta, Coincident etc.
Please offer me your suggestions

No,Onhwy61, I am not saying that at all. As I already indicated in my earliest post I am already assuming that recordings and equipment are of a certain caliber.

And by that I am implying sibilance is not embedded in the recording to any appreciable degree.

Dont waste time with AC. Its the last thing you do and you do it when you have all the right gear. Dont spend money there unless you have the best source you can afford.
If you need to spend 1 K + on AC spend it on a better source insted.
Garbage in Garbage out.

Yes AC make a difference. But is should be addressed last or if fortunate enough first.

And yes the source material can kill you if its bad. New pop recordings are horrible.

Bob B., please explain exactly where you disagree with Natalie's statements. Natalie may be blunt, but I don't see where anything he's said above warrants such an outright dismissal.

Dedicated circuits for cleaner power are a farce, in my opinion. Here is why I think so.
My living room light comes on with the timer tonight. The light bulb blows instantaneously while I'm listening to the stereo and my speakers go "phlam!" Not pop, even bigger than that.
My setup is a dedicated circuit on the opposite side of the circuit breaker box than the living room circuit. Furthermore I have a Tripp-Lite Isotel surge protector. The bulb blowing was probably too low to trip the Isotel.
Obviously all the circuits in the house are interconnected so I think this "dedicated circuit" is a farce. If somone can explain otherwise I am open to that.
The only reason I can se for dedicated circuits is so you don't get a voltage drop when the A/C, etc. comes on.
