Lifters ForGetting Cables Off The Floor, Worth It Or Snake Oil


  •  I'm looking at some porcelain cable lifters to get some power and speaker cable up off the floor.  Does raising the cables off the floor really make a difference? It's going to be about 200 bucks for 10 of them. Thanks.

@audiopoint the time base on the scans I posted is 160mS hence the frequency of the main signal visible in the first scan is 10-12hz (depending on whether you think there are 1.5 or 2 cycles displayed) so I suspect this is not a power supply issue. Nevertheless cognizant of the issue you raise the manufacturer does offer an external power supply in order to eliminate this possible source of additional interference - or as Herzan put it "EMI noise and heat"

my room unfortunately is of typical domestic construction (frame on slab) and my wife and I can feel the whole house shake with passing traffic and other subsonic activity. Perhaps other situations would not be as sensitive but I have found all of my equipment benefited from some form of isolation from the floor (be it via springs, roller balls or active isolation).

in terms of where the cognoscenti are at the platform of the moment is the Stacore combining pneumatic isolation and rollerballs. You may find this thread of interest

Someone would have to be living in a cave to suggest that real isolation and effective isolation - such as exemplified by the LIGO project - is not applicable to audio and to suggest that all you need is mechanical grounding. I’m afraid this is just a sad case of being almost entirely ignorant of what’s been going on in the industry outside the confines of one’s own narrow little developments. A perfect example of what I call Stove Piping, which is working in one’s own narrow little chimney, or stove pipe, and frequently arriving at some bizarre conclusion, not (rpt not) having the benefit of all the other developments that have been occuring outside that narrow chimney. It’s a crisis of Intelligence, information.

Real and effective vibration isolation has fortunately been available to audiophiles for more than 20 years, starting with Townshend’s Sesimic Sink, Bright Star air bladder and sand boxes and Vibraplane air bladder stands. My own single air spring Nimbus more than twenty years ago set the standard for number of degrees of motion and resonant frequency. The guys from Audio Point can save a little face as I’ve always maintained that good mechanical grounding techniques are important, too, especially in terms of grounding the component to the isolation device and grounding the iso device to the floors or support structure. The reason why isolation is used in the construction of tall buildings is to make the buildings less vulnerable to the effects of Sesimic vibration, especially earthquakes obviously, but also the effects of wind. I’m afraid a program of mechanical grounding as theaudiotweak suggests would turn out quite badly for tall structures, just as it would if applied across the board for audio.

folkfreak is in one of the most extreme construction-active cities in the U.S.A. right now---Portland Oregon! There is active construction on just about every street in the city. I go into town a few times a week, and am relived when I get back to the Salmon Creek area of Vancouver Washington, about a 20 minute car ride away. Peace and quiet! Plus, my electrical power station is only a 1/4 mile from my house, in a neighborhood with residential housing only---no industry, even light. More quiet. Makes my tinnitus even more audible!
Fifteen years ago a audio buddy came to me to ask advice on what to replace his CJ MV 75a tube power amp with. Have had the same amp previous I knew what it was and how to make it perform better. Instead of beating him up to buy a replacement amp..I sent him home with a Sistrum Sp1 platform so he could direct couple his power amp to his floor or shelf system..I don't remember which it was. 

He called me the next day to tell me he no longer needed an amp and thanked me for the transformation that occurred when he removed the Townshend Seismic Sink and replaced it with the Sistrum Sp1.The fat bass blurr was  gone the stage was more open and defined and there was an impression of greater dynamics and power. He said he now knew what the amp could do and thanked me for the advice and for saving him a few large. Cliff still has the amp (re-tubed) and still has it atop the Sp1.Tom

Tom, big deal. Even if it’s true, which I seriously doubt.
