Best Isolation HRS? SRA? Zoethecus? Symposium?

Mrdavid, I think the thread is long past what you are concerned about. Perhaps, Avphile reintroduced it.

Elberoth2, I hesitate to suggest various active isolators because of their cost, but they are the only solutions I know of. I have also found the Acapella base to be capable of isolating the component as well as absorbing the component originating noise. It pales in comparison to the active units. Yes, I use the expensive Halcyonic Micro 40 under my turntable.

Tbg - I think that absorption is not exactly the same as coupling to the ground. What we would need here, is not absorption, but some kind of mechanical diode (if such a thing exists) which would only let the vigrations travel in one way (from equipment to ground).

BTW - did you have a chance to compare Halycronics to Minus K platforms ? Is Halycronics weight specific (like Minus K) ?

Elberoth2, I am suggesting here that grounding of the noise of the device through rigid supports can be achieved by an active device which also provides isolation through the structure of the shelves and room. I know that spring devices can also absorb noises from components, which causes them to vibrate somewhat or to turn the vibration into heat. I don't think this meets the intent of grounding to the earth's mass or even flooring.

I am aware of the Minus K devices but have not tried them. At their root they are spring isolators, as I read the technology. The Halcyonic device is active, and the Macro 40 can take up to 300 pounds with self leveling.

I must say that I was so blown away by the Halcyonic, which I was allowed to try, that I explored no other professional devices.

Was the Halycronics worth the (high) price of admission ?

Don't you think that spending that money on other components could be more beneficial (you could buy a better pre, amp, speakers etc.) ?

Guess my last post was denied by Audigon, I'll try and rephrase. First I thanked David for his post and do appreciate that not everyone can afford, or think a $5000 isolation device is worth the funds. We do make the passive version at $1850 which is sonically identical to the active version except without the compressor. The active is more convenient and that's it. Once someone hears what the VP actually does they usually buy a 2nd or 3rd unit, we actually have a customer who now owns 13 units in one system! A world record I would think. Our US government just purchased another 8 active units. (Thank you Uncle Sam). So I do respect and understand these expensive devices are not for everyone, neither is the $8000 unit Norm has talked about, one that we also sell but even I don't think it's worth the extra $$$ over the standard VP.
A very Happy and SOUND New Year to all.
