My Rogue 99 needs better isolation...please help.

Thanks to everyone for the suggestions. Jphii-I'm using Ken Rad VT231'S with Halo rings which helped with the microphonics. Maybe I should try different tubes? Suggestions? Jeffcott-Where can I find info on the IsoBaseK and would a base with sand work better than a maple base? Are the Ceraballs considered a decoupling device? Finfinder- Which tubes are you using in your Rogue 99 and what does the rest of your system consist of? Thanks again in advance!

Thanks again for all of the suggestions! Has anyone tried Herbies feet or the vibration isolation pads from member rcreations? It sounds like Sylvania tubes are the way to go and I'll keep my eye out for them. Jphii- Wow...I couldn't believe how much the tubes went for in the link you provided. What are the sound differences between the Syl wgt's and the Syl w's metal base? The maple base I'm interested in is from www.timbernation.com, but there is also a picture of a sandbox that was made for a customer which looks really nice. Decisions...decisions.

All the suggestions were very helpful and much appreciated! I'm going to try some different tubes and a isolation product such as Bright Star air platform under the pre and probably one under the cdp. Happy new year to everyone and thanks again!
