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.

Email me off-line, and I will forward you some further information on the IsoBaseK: white paper and such. Both Bigkidz and Rcprince have had success with these units.

Regarding the several suggestions of Herbie's dampers,I am in complete agreement. Just started using them recently myself. Nice product.

Regarding bases with sand; I have not tried this myself so I cannot comment. I do know that I have seen some very well done DIY racks that employed this approach with good success. If you are interested, email me with your address and I will forward info (I think I kept it).

Regading Hebie's feet, I know that Rx8man is getting ready to try some variations of this product. Hopefully he will chime in with his observations.

My recent experience with tubes has been to have seen the eye opening differences (in my system, etc) that good isolation can make. Yes, I believe in tube dampers, but dampers alone (for me) don't come close to what isolation can do for some (not all) tubes. This recent experience has been with the 12AU7 family, but my guess is that the same rules apply to most tube families and the variations in manufacturing.
Just my two cents worth, but Jeffcott may be right concerning the townshend seismic sink and k-works osobase K. Sand works quite well for bleeding off vibration, but... alot of people use seismic sinks for turntables. If it works well for turntables, it shoud work well for tubes. Also, a symposium ultra platform with rollerblocks would be great, but the price on that combination would be $850 or more. A lot of choices. Best of luck! Stan
One further comment I will make, particularly in response to Talon's remark about using Seismic Sinks under turntables. When I first got a "Sink" my perception was that the most logical position was under my transport. This was nice, no question. When I got my second, I figured I would just "try" it under my DAC. WOW! The sink under the DAC made much more of a change than the sink under the transport. I must say that I would not want to go back to the DAC without a sink.
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!
