Adam, the black raviolis do work under tube gear. When I had my amp serviced last year I demoed them under it with positive results, especially with piano music.
I did not purchase any because I already have BDR and Hrs isolation and platforms. I have seen them used between binding posts and ic plugs, under speakers and wherever vibration can be a suspected problem.
