Isolation and Harsh Highs?


Hello I isolated my tube preamp with some equa footers. I notice a lot more detail and the sound is much cleaner and focused but I also notice the high are now kinda of harsh. Currently my system is on Lovan glass shelves and I have a couple maple platforms coming which will hopefully help matters. I would imagine the isolation revealed some brightness in my system I had not noticed before. Any ideas?

My System is
VPI Scout/Blackbird Cart/SDS/on Ginkgo Cloud 9 Iso platform
Granite Audio 770fp preamp
B and K Reference 2220 Amp
AQ Diamondback IC
Sonus Faber Concetos on sand filled stands
autodexr

..about medical grade lexan....very pure, also very expensive. This stuff is used in heart/lung machines. I made shelves from these, and all of my components are resting very comfortably on them. I tried many, many materials - 30 or so different woods, plastics, metals, etc. Teflon works well, but for my system I like Lexan. I used to sell this stuff to Hi-End shops. Support the shelves with cones - great sound.
