Vibration Theory - Isolate or Drain?

Pubul- I never damped a tube amp chassis, only CDPs and pre-amps. I also packed rope caulk around the transport mechanism.

With amps, I usually try to drain out vibration via cones onto a constrained layer platform (Symposium),especially when the Ps and transformers are mounted on the bottom plate of the component chassis.

This is really something you have to experiment with.

Addressing your initial question about isolating/damping CDP against vibratipn, I do both. In the few CDPs over the past 23 years, I’ve dampened the chassis with rope caulk or Mortite. I started using Mortite on the underside of my Denon t-t back in the late 70s with good results, so I was anxious to use that on the CDP. IME, all aspects of the sound improved. I also isolate the CDP using Symposium Rollerblocks which further improve the sonics.

Try the rope caulk. It will cost less than $10 to do your whole player.if you don’t like the sonics,simply remove it.
