The Best Isolation/ Vibration Footers per component - what's your experience?

I use a combination of isolation for my system. Under server: Stillpoints Ultra 6's / amp: Critical Mass Black Diamond shelf & Center Stage footers (4) / Under speakers: Nordost SortFut / REL subs: Arya Audio RevOpods / Under conditioner, grounding station and other conditioning products: Ultra 6's and Nordost SortKones (TC).  

I have mixed and matched all of the combinations possible with these products and have my preferences.  

I find the SortKones (TC) and the RevOpods equally effective with the RevOpods being warmer and the SortKones (TC) being a little more detailed. SortKones are tall and components tend to slide around a lot. RevOpods are much shorter but also have a hard surface on the narrow end (component side) so components will slide around if pushed or not handled carefully. If space (height) is an issue, the RevOpods will be more accommodating .

The Stillpoints Ultra 6's and the Center Stage footers were far more effective than the above. The Ultra 6's are extremely detailed, focused and somewhat analytical. The center Stage footers (1" & 1.5") are just as detailed but add a warmth and realness that the Ultra 6's don't. The holographic layering of the soundstage with the CS footers is spooky good. After talking with other Critical Mass owners and dealers I decided to add a Critical Mass shelf to the mix. Using the shelf in conjunction with the CS footers was cumulative and by far the best I have ever heard under a component. I plan to add 1 more CM shelf and 4 more CS footers.....Critical Mass is ridiculously expensive but nothing comes close to what their products can do for your system.

I got the RevOpods specifically for my 2 REL subs. I couldn't find a footer with the screw size that would accommodate the thread of the REL. I wanted to use Nordost SortFut (I use them on my main speakers) but Nordost didn't have a screw size to fit the REL's. I thought about Stillpoints Ultra 5's (they had the correct screw size) but I didn't want to spend that much on 8 footers (2 subs). A dealer who I have been working with for years had just become an Arya Audio distributor/dealer and was begging me to try them. He sent me a set to demo not only on my sub but he wanted me to try them on every component. My Innuos ZENith mk2 se music server is the most sensitive component I own and most telling of power cord, USB and footer changes, so that was the component I did my testing on. I tried 4 different footers under it for 5-10 days (each footer set). Nordost SortKones (TC) / RevOpods / Ultra 6's / Center Stage2 footers.

First of all I found each one of these footers improved the focus, imaging, detail and soundstage. In my system I preferred some over others. Every system is different and has different tuning needs. The quotes on RevOpods and Center Stage2 footers sound like what I heard in my system. 'Intoxicating' would be an accurate word to describe the Center Stage2 footers. In my system I thought the SortKones and the RevOpods were equal with slightly different tonal characteristics....SortKones being a little more detailed and the RevOpods being a little warmer.

I found the Ultra 6's and Center Stage footers a class above the RevOpods and SortKones. If your system is warm and tube like I could see you preferring Ultra 6's. If your system is neutral I could see one preferring Center Stage2's....again what you prefer will be based on your room, components, musical taste and what tonal qualities you desire.

One brand of footer might work well in my system and not be ideal in yours. I recommend finding a dealer that will let you borrow a set or two to demo in your system. Good luck finding a Critical Mass dealer that will let you do that (I couldn't find one). If you PM me I will give you the name of my dealer who sells Nordost, Stillpoints and RevOpods. You might be able to demo a set of RevOpods in your system.
