Isolation for power line conditioner?

I did not imply that I was unconcerned about power cords, "flapping in the breeze." Every cord and interconnect in my system has a Rightway Audio Suspender at its center. This helps both for the vibrations but also for the bleeding to ground. The topic, however, was whether there was benefit for isolating ac filters.

OK, maybe substantial and significant, as far as the power conditioner go, are a bit strong. It's worth the $$, to me, for the upgrade in sound. Cdp and amp? there I'll go with substantial or significant. peace, warren

I have measured the effect of Sistrum under my cd player, amp and pre-amp..with a 1.5db increase in gain. I have a LGE power transformer in my side yard 30 ft. from my main breaker box..I have never found a line conditioner that did not screw up the sound of my system..However I have sold Sistrum to clients who have used them with their line conditioners and they have stated they heard a marked improvement. Tom...I represent Sistrum, when people try it they keep it.

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?

Or your ears are better than the measurement equipment.
