Isolation platforms: TW Raven, Shindo

Greetings. My next step seems to be to get better isolation. I had designed my rack to "float" wood platforms on Finite Elemente cerapucs within the structure, but I'm thinking it wasn't the best idea (these used for my Shindo pre-amp and amps). I use slate under the TW Raven AC currently.

Here's what I'm thinking:

- get a SRA platform or an active/passive vibration platform (and have a wood frame built to make it look less industrial)
- I can't fit SRAs in my cabinet (too high with the equipment on it) to replace the wood platforms (above), though that would be ideal for a consistent look
- replace the wood platforms and cerepucs with something like the HRS platforms? These seem really ideal - if they work.
- I've tried the cerapucs under the preamp directly (sounds fine, but not an improvement), so not going down that path.
- I've tried the cerapucs under the amps, sounded bad/harsh
- I recognize "shindo belongs on wood" theory, but I'm looking to see if anyone has ventured off the beaten path (I'm not arguing it doesn,t, or it shouldn't, just asking if anyone has tried something else and the feedback)

Thank you for your insight/thoughts. All the best!
