Isonodes and Isopods under everything (including Isopods under my Silverline Preludes). The Isopods are so sticky they keep anything exactly where you put it...my DAC could withstand a pipe bomb. Be sure to note that too much isolation can cause components to become lonesome and depressed. Also, I play electric bass and guitar (frequently) through high quality "combo" amps (mostly)...there's your isolation paradox! My "boutique" little all tube guitar amp must be torturing itself, but since it sounds great I just look the other way.
