Cheap Tweak..Mass Loading

If you are dissatisfied with the sound of your system, try this before spending big bucks on upgrading of audio components. I borrowed 3 bags of lead shot (25 lbs) each from a friend and placed one on each of my 2 power conditioners (one for power amp and analog sources and one for digital) and a bag one my power amp. The improvement in sound was very dramatic, bigger than component upgrades that I have done in the past. Soundstage is huge with more depth. Dynamics at high listening levels is unbelievable. Resolution and detail at low levels is amazing. The bass is so tight it's like a sledge hammer hitting you square in the chest. For $45 I have seen a much bigger improvement in my system than I ever dreamed that I would. If you have not mass loaded your components..Do it!

My findings support Albert's statements. This does not work on all things equally well and the weight needs to be varied somewhat. Doing this in conjunction with other tweaks can add up to a noticeable difference. Sean

If I brought home two bags of lead shot and tried setting them atop my components in the livingroom I imagine the wife would be out in the garage looking for BUCKSHOT! I don't think I need to tell you where that would be headed:~)

You can also try using sand abrasives used for commercial sand blasting.

glen: as albert & sean correctly note (of course) this doesn't work on all components and the critical mass my vary among the components for which it does. once you determine on which pieces mass loading works and the amount required, you can have the shot sewn into quite a lovely custom bag, matching your curtains, upholstery or whatever. see, again, marthastewart.com (i'm lobbying a'gon to link to martha's site; i think it's indispensable for discriminating audiophiles). perhaps this may be a perfect place to involve your spouse more in your audio hobby. perhaps not. -cfb

Thanks CFB! Oddly enough while I was at Martha’s web-site picking out some lovely fabric, I went ahead and purchased a few matching throw pillows for the couch. I also hid the buckshot as a precautionary measure.: ~)
