I actually think those
Tibetan bell thingies are pretty cool, and they sure are pretty. I tried the Synergistic Research
MIG: Mechanical Interface Grounding devices, and while not bad, I do not find them as effective as Herbie's Audio Lab Iso-Cups. They are, however, quite cool looking. I know that others disagree, and I respect their experience.
In either case, however, I do not know how one could argue with the CCE or Hazen Grid Mod. It makes a clearly audible difference in Decware amps. But perhaps Walt is just having fun with us, eh?
