Best Isolation HRS? SRA? Zoethecus? Symposium?

I have a question to ppl wiser than me on this subject.

What is the prime function of equipment supports ?

Should they isolate the equipment from seismic vibrations ? Or maybe on the contrary - they should couple the equipment to the floor, like some of the manufacturers seems to suggest, to create a "drain path" for airborne and electronicborn vibrations.

Tbg -> can you name those solutions ?

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) ?

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.) ?

From hwl SCIENTIFIC INSTRUMENTS GmbH web site:

1987 John Sandercock founded JRS Scientific Instruments to develop active isolation systems for the growing market

1991 Introduction of the modular system MOD-2

1995 Introduction of a self-contained unit MOD-1

1996 Worldwide distribution by efforts of Herzan and Halcyonics. The cooperation between JRS and Halcyonics did not developed as intended and ended finally in 2002

2002 Halcyonics bought the non-exclusive rights to the MOD-1 and MOD-2 technology from JRS.

It seems that Halcyonics product is indeed not the same.
