I have heard isolation make "changes" in performance on transports, preamplifiers, and power conditioners. Don't ask me to explain it. I have not tried isolation on amplifiers yet.
Unfortunately most of the non-platform isolation devices I tried hurt the sound. I said "most" since some did actually improve the sound.
I think it is more than just component specific. Nobody ever mentions the rack and shelf material being used but I think this would have to enter into the equation. Meaning an isolation device that works on a component on one rack may give different results on the same component on a different rack. Platform devices may be more consistent than non-platform devices. Just my opinion at this point. Not something I have fully explored.
