In the sand box

Sand in the bottom of my Vienna Acoustics Bachs made a difference. Tighter more solid bass. There’s a plug in the bottom and a chamber built for sand. The owner’s manual describes what to, how to load em up. Also loaded up bookshelf speaker stands with sand, works great. You can buy “sterile” beach sand on Amazon designed just for such purposes. 
 

Hey, if it sounds good/better, then it works! 

Here’s a post from 2004 by Barry, of Bright Star Audio.  He started tweaking in 1985.

Since my listening area is on a suspended floor, several of my components are on Bright Star sand boxes - along with aftermarket footers.

I had a Bright Star sandbox.  It degraded the sound of my tube amp, and did not help the turntable,
