I am not sure I would use your multimeter as indicative of the limits of scientific measurement. Depending on the length of the cable and how far you lift it, it could easily make 10s or 100s of pF difference. Completely irrelevant to the sound, but easily measurable by any decent capacitance meter.lindsayt said:

I have left my home custom made acoutic objects in place *smile* because they work extremely well and I have hung the RPG BAD ARC panel to the ceiling at the first reflection point.
The other BAD panel is a huge it's 100mm thick and very heavy and I have placed it behind the listening position in front of the bi folding doors.
I bought them from a recording studio that has moved to a much bigger purpose built studio.
They have made a fantastic improvement to the imaging and detail level , the acoustic decay is as clean as a whistle plus a lot more focus.
I will post some pictures later .
I wasnt suggesting taking the exisiting out at this stage - just a comparison of the effects of pro built panels that have a designed in specific effect to ones that dont 🙂
Have you done any measurements yourself?andyjm said:
Or do you know of anyone that's measured this capacitance difference?
Whilst lifting speaker cables might make as much difference as 10 pF, it's also possible that it might not.
And would any measured changes from lifting be swamped by things like changes in the cable temperature - eg from running it next to a radiator?
Agree, old technology. Pointless baloney in my view and who wants stupid stuff like that scattered all over the floor. The extent some folk will go to to relieve us of our hard earned money. Complete tosh

Gazzip,
As I posted above, given some knowledge and experience, there are a range of proposed modifications on this forum that fall firmly into the 'crackpot' category.
I think we would all agree that poking a needle in your eye is a bad idea - without in fact ever having tried it.
I am afraid that cable lifters are similar. Given some basic electrical knowledge and some experience I can tell - without ever having tried it - that it is a crackpot idea.

I have not measured the capacitance change by lifting a speaker cable, but I have measured significant capacitance changes made by moving cables around inside electronic equipment. Lifting a speaker cable will certainly change the ground to cable capacitance - inaudibly.
Temperature effects everthing when it comes to electronics. Warming the cable will change its dimensions, and everything (capacitance, resistance, inductance) will change. Measurable, but inaudible.
Best thing to do with a speaker cable is not to put it on stands, but to cut off any excess.
A short cable is a good cable.

Andyjm,
Your needle in the eye analogy is not relevant. Avoiding the infliction of pain on one's self is an automatic response we are all born with, or at least we learn very early on in our development that this is a bad idea.
You appear to have some (more than basic) electrical knowledge, and have therefore developed an "educated" opinion in this matter. This I can respect. Alas many of the others who are vocally poo-poo-ing the concept of cable lifting and are lambasting those who suggest it as a tweak, have a) never tried it so have no primary point of reference, and b) have no demonstrable electrical knowledge on which to make such an educated opinion.
That, good sir, is pure uneducated bigotry which is something that gets right on my nipples.

In Sir Isaac's case, I think it was around his eye, not directly in it. I recall reading that he went partialy blind for a period of time after this experiment.

Ok, let's say I've got the first three sorted. Little tweaks now nothing major. Maybe a couple of bass traps and sorting out proper room correction filters in DSP which I decided I will be using.ellisdj said:
Is Mains really next? I was thinking Isolation... particularly under speakers. I've built a tack recently and I'm happy with improvements. And yes they are measurable.
My gut feeling more than anything and then cables with mains last. Advice would be welcome.

I've yet to see any technical data to back up the cliams, for or against. Could someone provide some? Until someone does, i'll put it down to psychoacoustics.

I once used to think that those of us who know better have an obligation to protect the vulnerable/uninformed from their own naivety, and with that in mind, these kind of products, along with daft mains cables, £250 fuses and audiophile-calibre USB/LAN cables deserve to be properly and publicly outed as the cons that they so are.
Then I joined this place, and got a rude awakening. Because when I first told someone hey you are being royally screwed, spend your hard-earned on something less sketchy (I forget the exact circumstances), I was told in no uncertain terms to go shove my advice where the sun don't shine. And I don't mean Glasgow.
So these days I'm like, you know what...you want to be gullible and waste your money? Go right ahead. My regret? I didn't think of all these money-making scams first.
