Well, since I mentioned the VooDoo Cable "Iso-Pods" above I wanted to add some info now that they have arrived.
These are very interesting. They are similar to Herbie's Iso-Cups and also Roller Blocks from Ingress Engineering or Symposium. But unlike the Roller Blocks they don't allow any noticeable latteral movement, they have a magnetic field holding them together pretty solidly.
I was hoping I could put these under the CSP2+ and ZP3 and they wouldn't wobble or be too low that the AC-12 power cords would cause them to move or lift. Well, success there, put these under the preamps and they are solid. But. . . I didn't like the sound that much. The quick and warm bass was just gone. Puzzling. Very clear and open midbass, great treble, but bass. . . vanished. I messed about a bit with controls etc. but never quite got close to what I had before in the lower frequencies. So I put the Tenderfeet back in, there you go, the bass was back.
I have Iso-Cups under my Power Plant Premier but wasn't sure they were doing much. So I tried five of the Iso-Pods under the PPP and was very surprised. There was a more open midrange and no loss in other frequencies. And then I had freed up five Iso-Cups with Deep Moss Quartz balls and had another one in the closet so I tried them under the two preamps. This time, since they are sitting on a PowerBase, somehow they wer quite stable on the Iso-Cups, and the sound now was just great. A bit more depth to the sound with the right tonal balance and seemed a bit more revealing of dynamic changes. Okay, I stuck a fork in the mix, done. Very happy with the improvements, certainly not earth-shaking but what is?
Next I replaced the four Tenderfeet under the Rega RP3 with four of the Iso-Pods. No question, the Iso-Pods win. More depth AND more detail to the sound. I liked the Roller Blocks under the RP3 but could not live with the latteral movement when they were there, not on an turntable! No such movement with these.
So the Iso-Pods surprised me, didn't like them under my tubed preamps, really liked them under the PPP and the RP3. Interesting pieces.
