Hi Psag,
I'm right in the middle of a very extensive process of reviewing isolation devices for a review in the future for my website hometheaterreview.com. I have had in house many highly regarded footers, platforms, and racks to see what their effect would be on the performance of different gear and speakers. The results so far, will not surprise seasoned audiophiles, is that you never know what the results to be until you experiment in your own system. Some of the most highly regarded and expensive platforms/footers sucked the life out of my system, while other less known, less expensive devices produced wonderful sonic changes like more transparency/micro-details, better sound staging and layering, more accurate/taut extended bass, etc. The two very big winners so far have been: 1) For all upstream gear the rack and footers from Krolo Design. No matter what piece of gear I have put on the Krolo rack or footers it always has lead to significant improved performance with no negative effects at all. 2) For speaker isolation the Sistrum Apprentice Platform/Audio Points from Star Sound Technologies, which is not even this company's reference level device, had a beautiful effect on my Lawrence Audio Cello Speakers. Both company's offer home audition periods and charge very reasonable prices for their very high quality devices. Hope this helps, good luck with your experimentation.
