Isolation for power line conditioner?

onhwy61, it's been my experience that in a well-assembled system, nearly every positive system improvement is significant and substantial and rather easily acheived.

I believe that would seem logical and I'll demonstrate by using the following analogy:

If I were racing an old jalopy that had an out-of-round wheel, I might not even know that the wheel is inferior even at top speed. But if I were racing a finely tuned Indy car and I had an out-of-round wheel, I'd probably recognize a problem before I reached 10 mph.

And if I'm racing that Indy car at 220 mph but corrected the deformed wheel, that car's performance improvement should be rather significant and substantial in comparison.

In other words, a well-assembled system as you put it, should have fewer and smaller bottlenecks/governors.

But properly addressing just one of those fewer and smaller bottlenecks can be akin to completely removing a govenor.

Whereas a poorly assembled system with so many governors, properly addressing just one usually makes little or no difference.

That is why I believe so many people try a new product or tweak, don't notice any improvements, and then make sport of those that do notice a difference as if they've bought into a snake oil (of course snake oil products can and do exist).

As for your issue with dangling cables being susceptable to air-borne vibrations? I'm not that familiar with the issue but I realize that it is a potential area of concern.

Nevertheless, by it's constructive nature and shape, a cable should be less susceptible to air-borne vibrations than a larger square boxed component that may have minimal internal bracing, as well as a cable not having a motor, spindle, transistors, capacitors, power supplies, etc..

Though a cable's reaction to vibration is still potentially valid, I don't think it's quite to the same degree.

And again, on that truly well-assembled system, properly addressing vibrations within the cables could make a rather significan and substantial difference.

-IMO

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?
