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?

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.
I tried quicksand, and it was great for the 45 seconds that the CD player stayed in sight.....
Grungle,

I'm actually using Silentra's Diagrit series! I first used the NORMAL sand that I had brought home with me from Florida, then I decided I would upgrade. Like you said overall the presentation was much finer grained than with the regular non audiophile quality sand. I think everybody should have Diagrit in their system. I second Grungle, best $1500 I ever spent!
Buckingham, BIG mistake with the Florida sand, far too coarse for your purposes. If you can make it to the Sahara, now there's the ultimate...
You guys are all GOOFS !!!! Everyone knows that sand will add "grain" and "grit" to a system. It can also sound very "dry" and "bleached".

Your best bet is to use clay straight from the banks of the Mississippi. The soundstage will fill in with far greater "density" while also being "wetter" with increased "liquidity". The sound will be so "moldable" that you will think that the performers are present in the room.

The increased cohesiveness may be due to the fact that the clay will act as one supporting structure rather than the sand acting as individual grains, all with different ideas and motives.

Some folks claim to have had good luck with "moon rocks", but i don't believe them for several reasons : ) Sean
