vibration and resonance

Ikea in your area buy lack tables. there based on the torolyt stands that were built for linns during the late part of the 80s the principle was light yet very ridged structures are better at reducing unwanted vibration then massive solid struture. I think many have gotten away from this and have gone back to massive blocks of marble and slate are better controlling vibration?

Drtalsma:

Can you describe the actual rack you built. This might be useful for providing better comments. It's not that clear from your threads what finally you built.

Call Steve @ Herbie's Audio and talk with him. I'm sure he will have some worthwhile suggestions.

If you remain with your current rack DynaMat should improve it significantly. MUCH better than cork. However, once applied consider DynaMat a permanent tweak since it is not easily removed.

Both dynamat and cork stink.

Don't throw good money after bad. If your rack "rings", I suggest you go with something by the established manufacturers. I have a Salamander Archetype with cherry shelves that I am happy with, but would also look at Cambre, HRS and a few others if I was in the market.
