Anyone use CD tweaks


I was wondering about the effectiveness of products hyped to improved sound quality - i.e. products like Maple Shade's "Mikro Smooth" for polishing CDs and their "Optrix" surfactant product. You want to believe these claims, but sometimes they sound too good to be true. Anyone with any experience with these or similar CD enhancers??

Thanks in advance...

ditto with the disc damper but I use the Marigo Reference and yes it does make a difference. I also just started to use Ultrabit and for sure it does make an almost jaw dropping difference. It is a bit expensive ($65/bottle) direct from Manufacturer or $80-$85 from Music Direct but you can hear the difference the first time out. Also my CD sits atop Bright Star's Air Mass and Big Rock, again a "tweak" that makes a VERY POSITIVE difference, wouldn't ever be without them!
Update regarding weights on top of CD players and Amp/Preamps....not good, kills dynamics and limits transparency. I still use brass heavyfeet under CD player but not umder my amp/preamp. Mapleshade CD enhancement products work well to reduce digititis and add a bit more warmth and rosin to the music.
I used to have a bottle of Finyl and it worked wonders. I wonder if something similar is available today?

I also have a CD mat (blacklight?) but I am just getting too lazy to use it. I have to soak it under light so that that it glows in green .... ah .. jus too much work.
I just bought some Dynamat and put it on all open metal inside the case of my player. I also put it on the transport where it wasn't in the way of anything. What a difference it made.It absorbs the vibration on the transport. The bottom end is more musical, the mids and highs are even more transparent than before. I am telling you it is the best $25.00 I have ever spent. I will now put my Denon 1940CI up against any player under a grand.It really is that good. Can't wait for a opamp and better dac.and the transport is silent now.No noise when it opens or closes.
You should try $5 copper tweak here. It changes my whole system from musical and warm to a Hi-fi one. Not in a good way, not in a bad way, it just does. Now, I slide it back and forth from time to time when I want my music sounds diff.
