You might try what I did: place a group of Vibrapods under a piece 1/4" tempered glass, which has also been damped by applying a sheet of DexDamp (a constrained layer damping sheet, similar to DynaMat). DexDamp can be purchased by the sheet (about 12" x 18") from marine supply houses, and sometimes from car audio installers. I got mine from a marine supply place in Seattle called HamiltonJet. They have a good Web site with all sorts of acoustic control materials: www.hamiltonjet.com
CDP isolation options for improved HF?
Following recent thread on shelf material, I'd appreciate advice on supplentary isolation/vibration devices for my old CDP (Rotel 855). I'm mulling over new digital front end options, but meanwhile want to eliminate HF roughness now evident in my new ref system, without reducing PRAT or resolution. So how do I optimize the use of this CDP until the revolution? Some have suggested that air bladder suspensions compromise timing. Is this often true? Thanks. Ernie
