Isolation Sand Boxes


I built some MDF sand boxes and filled them with 15 lbs of sand. Why do they make my CD player sound quieter?

Hey guys, a nice end to my hectic day! You guys crack me up :)
Thanks for all the comments. A 3/4" MDF platform sits on top of the sand. The sand box sits on a rack (lots of MDF and solid woods). I decided that I liked it better without the sand box... The sand box just sucked the life right out of the player! Kinda weird... I might try the BD cones, maybe #4's and some lead shot on top of the player.
Hi Buckingham. Yes the sand boxes do such the life out. Personally, I believe you are right to try the #4s than the #3s, but my preference with BD Cones was 2 #4s and 1 #3. Another option, which is possibly better with a timber and MDF rack, is the large DH Cones, or the Walker Valid Points. But at that price you might be better to begin looking at a proper rack and the Neuance shelves. You ain't heard nothing till you have heard that.
I agree that the CD player does not sound good on the sand box, the amps do though. Though the sandbox does work well (with digital) when used with BD racing cones or even much better the Walker Valid Points
So you're saying I should keep the sand boxes under it when I get the MK4's?
Interesting. Tweaking is fun.
Well of course it's lifeless, you aren't using audiophile quality sand. Do yourself a favor and drop $500 for a couple pounds of Silentra Mass V sand.
I recently upgraded to their Diagrit series, best $1500 I ever spent. The imaging prolems that had plauged my system all but disapeared and my lower-mid resolution became clearer much finer grained. There's also a slight improvement in bottom end weight, although I'm sure it would be more if I had more sand.
