Until recently I owned a Rogue 99 Magnum and the best sound it produced was with the following: 2" hard maple shelf on top of Vibrapods with 1"x3/4"x3/4" zebrawood blocks between the maple shelf and the bottom of the 99 chassis (that's the chassis, Not the 99s feet) plus Herbies tube dampers on all four tubes. The biggest changes came with the Maple shelf and zebrawood blocks. In this application the latter were significantly better than BDR cones (either #3s or #4s)or Vibrapods directly under the 99. My wife and I did several evenings of listening comparisons and found that Zebrawood or teak wood sound best - clearer, more vivid, deeper and tighter bass, more effortless presentation. I know it all sounds weird about the wood blocks and I was skeptical even after reading the article in StereoTomes.com regarding electromachanical convergence, but there was a clearly audible difference; not at all subtle. And it is inexpensive to experiment with wood scraps from a woodworking specialty source.
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.
