Weights on top of equipment to dampen vibration

I accidentally found another (cheap) isolation fix.

I have a Zanden 5000S DAC with a very microphonic tube...waiting for tube replacement. (It is so microphonic, that the bass the combination of my SF Strads and Velodyne DD-18 sub causes to tube to whistle loudly through my speakers.)

Solution? I use a pair of ankle sandbag weights (the kind people attach to their ankles to work out) and I flatten them out and place them underneath the Zanden.

The combination of sand tightly bound in a heavy duty, extra tick nylon ankle band means you get both:a) vibration insulation from the sand b) fairly firm foundation because the ankle band keeps the sand from continuously shifting.

Nothing else I have tried keeps the tube from whistling thru the speaker. Hope that helps someone else out there!

It depends on everything. Your component and its case, what is under it, the metal of the case, the material of the weight, its location on the component, how it couples with the component, what the component is sitting on, what your flooring is like, where the component is relative to the speakers, how loud you play, what standing waves you have in your room, the positioning of the wires and circuit boards in the component, whether there are mechanical or ac induced vibrations in the unit, and your tastes all matter.

Trial and error is your only alternative. There is no reason to think that anyone's experiences here transfer to you and your system.

Tbg. Well said.

Tbg thanks, I was afraid that was the case !

Musicfile, look at it as an adventure. Whatever you try experiment with many locations. This is true also for feet under the components.
