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!
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.

The reason for my seemingly contrarian nature in this thread stems from the fact that Centurymantra already had a form of isolation under his power conditioner and the responses indicated that he would reap substantial and significant benefits by switching to an alternative form of isolation (or mechanical grounding). Some even offered explanations as to why their recommended alternatives would work better. My harping on the cables and electric panel is to simply point out a weak area in their explanations. If vibration is a problem, then address it everywhere. Anything with mass is subject to the forces of external vibration, cables included. And yes, basements filled with mechanical equipment (furnaces, water heaters,, well pumps, etc.) subject the electric panel to vibration. Or just maybe, the farther away you get from components (I use the term all exclusively) that are directly in the audio signal path, the less benefit isolation becomes. Is it totally unreasonable to suppose that a power conditioner is far enough out of the signal path to not warrant sophisticated isolation techniques? If it's not, then where do you stop?

If my name is a disservice it's a disservice to Sunnyland Slim. Mr. Dylan only revisited the highway which originally Sunnyland rode. Also, what I lack is gullibility.
My electical panel box is coupled to the wall in my audio room with Audiopoints as are all my audio components with Sistrum. My video projector is coupled to the ceiling with Audiopoints as well as the acoustic lenses I built and installed on the ceiling,on these 33Apcd coupling discs were used with 33 .2in discs. ....Tom
I would have thought the thread on magnets would have attracted you away from your aquatic origins.At least sucked all the ferrous materials from your lair..That would be a good thing. Are you now thinking outside of the fish tank? You have all the answers already..Your name says it all. It must be so..Tom
