Right, Barry's studio is very well laid-out with attention to signal noise, isolation, power quality, etc. He pays attention to detail and he's not "hide-bound" by any rules other than what his ears seem to tell him.
I have read of Barry's "hip joint" isolation devices for years and my main problem with them is that he always anchors a smooth concave metal surface to a wood block base, and that combination raises the speaker height which for my seating position(s) and the tweeter height of my speakers doesn't work out well. So I got to thinking that with the sort of "compressability" of the surface of my carpet the steel concave piece will be well anchored by the weight of the speaker. Barry uses 1/2" to 1" steel ball bearings in his design, but I know how neutral in signature the acrylic balls that Steve Herbelin used to use in his IsoCups are, and I had eight of those handy, so I thought I could use those. So I bought a dozen automobile engine freeze plugs, they have a polished smooth concave surface, and just put those down on the carpet near the corners of the speaker and put the acrylic balls in the center, and placed the speaker on these. It takes some time and a bit of frustrating energy to find the best balancing position for the set-up, and to get both speakers toed-in (or not) and properly positioned, etc. so you want to sort of get it right quickly and not mess with it.
Barry's assertion is that the speaker's vibrational energy is absorbed by the ball moving even the tiniest amount within the concave smooth surface of the bottom piece. There is a very expensive highly machined bit of audio bling like these that you can purchase but this is a twenty dollar tweak, much more affordable. I think the reasoning is sound (sort of like the Aurios ball bearing footers or other bearing and cup footers, and the IsoCups, though within those the ball really can't move unless large force is applied). Barry thinks that isolation such as this is better than coupling speakers.
Anyway, I had interesting results with just the acrylic balls on the carpet when I first got the speakers but I decided that some sort of tonal linearity was lost and just had the speakers flat on the carpet. With this set up, adding the freeze plugs seems to allow the balls to move freely enough, and the change in sound seemed more linear. I'm not sure I have the speakers exactly where they are at their best with this set-up, and will probably play with location over time. But I like what I hear, and I would say the biggest changes are a sweetening of the treble and a bit more soundstage imaging detail (though I am not sure that is anything more than subtle). Fun to play with, I really enjoy isolation components and their effect on my system. A friend thinks that it is because of my pier-on-beam foundation old creaky house that these things seem to make a difference, but he hears it too and we both find less of a change using these in his concrete slab apartment. Anyway, this is something to keep the boredom away! In time maybe I'll think of or stumble upon a bottom piece that works better in this set-up, or try smaller steel bearings. . . I think the steepness of the curve of the freeze plugs may be limiting the movement of the balls (?)
