RE: Cable elevators (lifters)

I did not buy cable lifters but just experimented using a number of glass ramekins from my kitchen. I left them in place for a few weeks but I wasn't too sure that they did anything at all until I removed them.

I was pleased to remove them as they were not exactly the most eye pleasing arrangement. After a day or so I realised that my system just didn't sound as good as before especially in the area of its ability to throw a convincing 3D soundstage and there was a diminution of small dynamics making the music a bit flat or less exciting too. So back they went to be replaced later by some Cardas myrtle woodblocks with a large "V" groove cut to hold the cable, not because they "sounded" better but they just looked better. And they were not expensive.

There are three hypotheses that I am aware that have been advanced to explain the effect:

1. Electrostatic ( especially I guess where carpets with a high artificial fibre content are concerned).

2.As the electric field extends beyond the conductor that having air rather than carpet next to the cable is preferable.

3. That the floor (like walls) is at an acoustic pressure zone and moving the cable away from this provides benefits (I note that some proprietary cable lifters suspend the cable relatively high above the floor though whether or not for this purpose I do not know).

So why not experiment with some thick cardboard? I have seen some D.I.Y lifters made from the cardboard tube from the centre of toilet tissue rolls.

The effect is relatively subtle and presumably inaudible with a system that cannot throw a convincing soundstage in the first place, at least in relation to my my experience.
