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

I'm currently using ceraballs under a Rogue 99 and found them to better the BDR cones that I was using before. Although the microphonics are less pronounced than the BDR cones, I'm curious if a combination of four cork isolation pads under a maple board used in conjunction with the ceraballs would help with the microphonics. Any suggestions would be much appreciated.

If you do that you start mixing coupling & isolation. I don't know if the Rouge responds better to either system, but my preference is one or the other (coupling for me).

If you are getting serious microphonics, you may want to look to your tubes first. I used the KenRad VT231's in my Supratek, and they were my least favorite & noisiest tubes I've tried. I found this very strange since I love the KenRad VT229 in my Soro.

Ezekial had a great sugestion, the Sylvania WGT's. They work pretty good. But, the metal base W's, and the Tungsol round plate black glass are the reigning champs in the Supratek camp. Also the short bottle brown base Sylvania W's. I'm sure you would get the same results in the Rouge.

I imagine these should sound pretty good too, for what they cost. One other brand that I really like but can never find are Toshiba's. I haven't compared the plate structure to others, but they are a GTB with a chrome top. I was extremely surprised at how good they sound and also are as close to noiseless as you can get.

I only use the tube dampers on my phono tubes, but I imagine they should help also.
