Isolation for power line conditioner?

I have heard that many gain good results by providing isolation for their PLC units and was wondering what type of suggestions/experience folks out there may offer. I do currently have my line conditioner (Sound Application XE12-S) on a slab of MDF on aluminum cones. I put this together awhile back for the PLC I had at the time, and chose this route simply cuz I had the stuff lying around and it seemed to be better than nothing. That aside, considering this particular unit is, I believe, primarily a passive component, what solutions and ideas can you throw my way? Thanks in advance!
I have been selling electronic test and measurement equipment for the better part of 15 years. I sell some of the worlds most sensitive, high dynamic range spectrum analyzers in the world with bandwidths from 10 Hz all the way up to millimeter wave frequencies. These analyzers have dynamic ranges of 145 dB and noise floors of -130db to -140db. These instruments sometimes find themselves in both production environments (notoriously poor environments)and metrology lab situations (controlled near perfect environment). It's funny, but these analyzers don't have pointed feet or special power cords or power conditioners and rarely see clean power yet they always meet spec and look as spectrally clean as if they were in a perfect environment. Why do you suppose that is? Could it be that all the tweeks are just compensating for poorly designed equipment?
Good analogy Stehno, but you're contradicting one of your earlier posts. Either "every component is near equally susceptible to capturing air-borne vibrations" or they're not. I see no logical reason to except cables. Even though I say it somewhat mockingly, why wouldn't a house's main electrical panel be susceptible to the same claimed improvements heard by isolating and/or mechanically grounding a power line conditioner. The electric panel is just as much in the music signal loop as is the power conditioner.

Am I the only one would finds Theaudiotweak's comment about the effect of Sistrum platforms on circuit gain as absurd? As audiophiles are we so desperate for performance improvements that we'll accept any claim, no matter how lacking in logical explanation, as potentially true?
Let see I own an RTA and I play a test tone thru my system with out Sistrum..and I measure the output and I record it on the RTA..Ya got it?..Now I do the same except this time I insert a Sistrum platform..and I measure it and I record it..Now I compare the two measurements in memory and the one with Sistrum has more output....And now for even something more absurd at least to you with the name that does a disservice to Bob Dylan. I have developed an acoustic device for some acoustic musical instruments that greatly extends the frequency extremes, coherency, focus and the output by 55%..All documented in my provisional US patent application..with photos and recordings not required..Its so absurdly good that when I first heard it with my ears, tears escaped from my eyes. You Sir need to always doubt and have no imagination..Tom
Onhwy61, you do err in the assumption that the quote from my earlier post included cables. It did not. Sorry for the confusion and perhaps the word 'component' should always imply everything. But until now whenever I mentioned the word 'component' I always meant in the context of the traditional source, pre, amp, turntable, etc.. Thanks for pointing that out.

Also, my stance in this post has been consistantly to address the original topic of line conditioners, not cables. Others brought up the cables topic and I simply offered my very speculative opinion on that.

But thanks for validating my analogy.

For most, the eletrical panel is not located in the same room as the speakers. Therefore, it would odd to try to include that in your argument. And I still stand by my statement that to the best of my guessing, an electrical cable, ic, or speaker cable in the same room as the speakers simply is not going to capture the same intensity of air-borne vibrations as the cdp, tt, pre, or amp. But I don't doubt that cables would capture a percentage of that intensity.
