Equipment Set-up Recommendations?

Hi Folks:
I recently installed an air-bearing linear tracking tonearm (the MG-1). Table and cartridge are Teres 255 and ZYX Airy 3x-sb low output. Generally, I'm thrilled with the setup, but I find that when I walk around the room, the cartridge can jump, which is very disconcerting.

When I switch to the OL Silver arm I have, such jumping does not seem to occur, so I'm guessing the MG-1 is more sensitive. All my equipment is supported with the double rack, which may also be a variable to consider - I have my Teres on top - about 40 inches above the ground.

Anyway, I'd welcome any input or insight that migth provide me with a more stable, isolated listening environment where my cartridge won't jump (how bad is that for the cartridge anyway - should that be considered an emergency, or is it pretty common/not-a-big-deal? I've inquired about getting a Gingko platform, which may or may not help. Ideally, I'd like to keep the Teres on top of the rack, as it looks great, is highly accessible, and I don't want to take up more realestate with a seperate Teres stand, if I don't have to.

Anyway, any input and advice would be much appreciated. Thanks in advance!

John.

Userid, of course the Vibraplane is made by an industrial isolation company. So is the Halcyonics platform recently shown at the Stereophile show. I guess what is needed is a shootout although I never trust others ears.

I did go to the Minus K BM-1 page. THe BM-6's specifications are not the equal of the BM-1's. I don't know why these companies don't make a rack with this platform at the bottom. If it can be done, it would be more economical.

I gather that the Minus K BM-1 isolation platform is an electronic device. Long ago I recounted, for audiophiles, my experience with vibration isolation in context of using a large dish of Mercury as a reflector for optical work. Ripples on the surface of the Mercury were a big problem until we bought an electronic vibration isolator. The cost of a SOTA electronic isolator is well within the budget of high end vinyl fans.

Eldartford, the Minus K is a controlled spring device using no air pressure nor electricity.

Tbg..OK I found the website which has a good technical description. A very clever device. The picture I found earlier looked very similar to the electronic table that I used. And the price is about the same. The performance is also similar.

Eldartford, do you have a Halcyonics?
