Daedalus Audio had the ModWright Tryst vacuum tube headphone amp ($2995) on their DiD isolation devices ($480 for set of three). Daedalus Audio's DiD are audio footers that really do make a difference! They are said to be particularly effective under DACs, CD players, and tube amplifiers. The Chief Engineer at Daedalus Audio has always been skeptical of many audio tweaks and if they are really worth the money. Yet as audiophiles keep pushing the envelope to make recorded music sound 'real', he saw the need to look at every aspect of the signal chain. This is the kind of design philosophy that has the company constantly improving their speakers and investigating every detail that goes into the system. Their DiD device utilize dissimilar materials to dissipate resonance coupled with bearings to also isolate the electronic component from vibration. They are precision made of highly polished billet aluminum, solid Cherry and brass with steel bearings.
