Isolation Platforms...worthwhile?

i've had mixed results using DIY stuff (and this conclusion would be possible with commercial as well). I used an air suspension system under my CDP that tightened up the bass and mids to a nice degree but the upper octave completely dissappeared. the cool thing about DIY is if it doesn't work out you're not out much

Yeah, there's been a lot of discussion here on this topic over the last few years. Many varying opinions and different schools of thought. Run some searches in the forums.

For what it's worth, I really like the Neuance Shelf under my transport.

I also found the Neuance platform to work best under my CD player after many other evaluations.

Has anybody got any input on the Audio ref-or research brand sold here???
