Know of a "Dirt Cheap" tweak?

I had a problem with Sibilance with my Perreaux amp...the T's and S's sounding much too harsh and opaque. Then, a guy from this site named Sean who is a professional sound engineer set me up with Mobile Spec interconnect cables that were fifteen bucks a pair. I think this must be used in radio applications. He said that when he engineered the sound for several big name bands, he uses these as Sibilance busters. Plainly put, I COULD NOT BELIEVE THE DIFFERENCE. Sorry to harp time and time again about these things, but I think they just buried my more expensive audio interconnects. BURIED THEM. Others have theorized that what has happend is that the cables are poorly designed and they act as a filter for certain high frequencies. I don't know, maybe, but they made my solid state sound much more like my tube amps. And I could not notice any loss of detail. Mobile Spec Performance cables. Don't know where you can get em. Ask Sean.

See my DIY thread under the heading "Best wires for cost". The design that I explained costs less than $3.00/ft, yet it has beat up many $400.00 per meter cables, really!

Spend $35 for a copy of Robert Harley's book. "The Complete Guide to High-End Audio" (2nd Edition). There is so much great advise in there about absolutely everything it will be the best $35 you ever spent.

Sand in zip-lock bags to be placed on top of cd players, dac, speakers even sides of turntables to add some weight, this will cut down on vibration.

Finyl. It s a clear liquid spray you spray on Cd s and then polish. I ordered some from ufh magazine audiophile store one day when I was bored. I was expecting nothing but know they wouldn't use it if they didn't hear an improvment of at least a little bit. Cautiously I took an old classical Deutsche Grammophon and followed the instructons. I was stunned to hear an almost unlistenable cd/ very bright/ become listenable. I seemed to take the top end grain right off. Next I tried my new Patrica O'Callaghan. The speakers just dissapeared. The sound stage moved up, out and back. Seriously. I was sitting im my chair trying to figure this out. I looked again at the back of the instructions and it said "smooths out brightness and improves sound stage". I thought maybe it worked well because I only have a Marantz 67se cd plaver and it could maybe use some help. So I Emailed UHF mag and asked if my this meant my player needed upgrading. They said they had heard improvments in very high end players. How much I dont know. I have done about 25 discs now and notice It affects some more than others but when it works its not one of these tweeks you have to strain to know if its better. It really stands out. Galen Carol has a product similar called Optrix. He says he has not compared the two but has been told Optrix works better. The products are supposed to prevent laser light diffraction. Cheers steve
