Really cheap, effective tweak

I know there have been posts before about the rubber-cork-rubber "sandwich" isolation pads - found a place that sells them for $1.50 apiece (in multiples of 4 for $6) - just got 16 for $34 shipped. As far as I can tell, these are the same as the ones many places are selling at $24 for 4 or even higher. They work as well or better than any isolation device I've used. They also have bigger ones in case the standard 2" squares aren't big enough for you: http://www.soundproofing.org/infopages/vibrationpads.htm

Excellent! Order pending. Thanks Rich!

Oh, and Hi from the East coast (of State College that is). :)
 
Good one, I've also used those furniture sliders that you can finds at WalMart/HD/Fleet Farm.
 
nice

I have used these to surprisingly good effect in one of my systems. Whats also nice is that they are pretty large and easy to move around.

This IMHO is a must have in the audio accessories drawer
 
If you look at the photos I have posted of my room setup you will see that I use them under all my speakers. I love 'em...

Have you used them under anything else?

I have used them to good effect under CD transports and players, DAC's, preamps, and amps. My experience putting them under speakers was less than positive, but in every other case I thought they had a least a bit of a positive effect. Adjusting their position under my tube amp (Dynakit ST-35) allows me to minimize mechanical buzz from the transformer.

Nice - I plan to put them under one of my turntables, and some others under my CDP or tube preamp.
 
Just bought a set of these for the cdp. I'm curious. Thanks again Rich.
Besides, mabey we'll stay out of hot water...
 
I got mine a few days ago and I have them under a couple tube components. Hard to say for sure what kind of difference it made, especially because the one tube buffer is brand new, but looking at what these things are made out of I can't imagine they're not effective.
 
I'm certain that they will make a positive difference for most, if not all CDPs.

I Isolated a CDP using super balls, the small ones you get for a quarter at pizza parlors and the like, and it did make a difference for the better. I reported it here, and many others have tried it, and reported the same results.

For me it was just an odd experiment, and I was surprised at the results. My son was also involved and he also was hearing the difference.

Others have used Blue tack to deaden the interior of the mostly crappy plastic cases of CP and DVD players with similar results.

I don't for a minute believe it is improving the 0's and 1's, or how the laser reads them, but the circuitry after the D to A converter can be affected. Black magic for sure, until some smart boy gets to reading the output circuitry and discovers what the heck is harmonic enough to be affected.

I suspect a CDP on an already acoustically "Dead" surface would see minimal difference. But that is just a guess. My project for a well padded and dead surface for my sources to sit on s on hold indefinitely, so I won't be able to do much about further testing in the foreseeable future. My current CDPs are not using isolation only as they lack the headroom required for the balls.
