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

Hi Chuck I was skeptical too.
But having read so much here about the benefit I had to try it & they are SO right.
Not completely understanding something doesn't make it worthless; very few of us would even be driving automobiles if that were the case.

Cdc, okay, after you emphatically stated that cleaning the electrical for sonic improvements is a farce, you did state your one reason why.

However, I believe the reason you provided was poor in that 1. it was an abnormal occurance (when something like a light bulb blows) and 2. You spoke only hypothetically even though your light bulb may really have blown. You did not cite one practical experience where cleaning up the electrical would have any positive or negative affects on the sonics of your system.

Correct me if I'm wrong but was it not too long ago and yet even today, some to many claim that audio cables are all the same and make no sonic difference. Some say that about amplifiers too. All amplifiers simply amplify. With your stance on the above I must assume that you are in these camps as well. So are most electricians.

Your stance reminds me of the scientist proving that a bumble bee cannot fly theory. But that's all it is, a theory. Well, the bumble bees are flying and obviously some to many audio enthusiasts are experiencing greater pleasure with their systems than you are with yours.

As for asking an electrician anything along these lines? Unless it's Glen, I'd rather ask the kid at the drive-thru window at McDonald's.

An electrician is not an electrical engineer. And of course neither am I. But I play one in my house and here on audiogon.

I don't get it. 40+ odd posts later, and you guys are still going at it over the AC issue. Don't get me wrong, I do believe, based on experience, that cleaner power can = cleaner transients. And of course, no one can get rid of sibilance embedded in a recording. BUT THIS POOR FELLOW IS LISTENING IN A 26' X 14' UNCARPETED BASEMENT. HE HAS A SEVERE AFFLICTION OF FLUTTER ECHO, A PHENOMENON WHICH ANY PRO SOUND REINFORCEMENT OR STUDIO PROFESSIONAL CAN TELL YOU IS GREATLY EXCITED BY SIBILANTS, MAKING THEM SOUND WILDLY EXAGERATED. Attending to the AC or whatever else is all well and fine, AFTER TAKING CARE OF THE ROOM, FOR THE EMINENTLY SIMPLE REASON THAT HE WON'T BE ABLE TO FULLY BENEFIT FROM, OR MAYBE EVEN HEAR AT ALL, THESE OTHER IMPROVEMENTS IN HIS ROOM AS IT IS. Debate it all you like, but that's the honest truth, Ruth. (IMHO, natch! :-)

Funny, I've had conversations with others in large and very live rooms before, unfinished homes, empty cafeterias and church bldg's (well near empty) many times bigger than the 24 x 16 room mentioned above. And I've yet to hear anybody's pronunciation of the 's' sound turn to mush simply because of excited reverb, flutter echo, etc..

I don't know about wildly excited but all audio info becomes somewhat 'excited' in a acoustically untreated live room. Not just the portion resulting in sibilance. Our ears easily make the distinction as to which type of room we're in. The original source information does not change one iota. Only the reverb info. But again our ears most always can easily make that distinction between the original source and the ensuing echo.

I'd be curious to know the names of the 'Pro Sound Reinforcers' and 'Studio Professionals' that Zaikesman consulted regarding this matter.
