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.

Guys - just so you know - I'm not jumping around the room or walking close to the turntable as I'm listening ;-) However, it is necessary to walk towards the turntable to change records, and walk back to listening position. Also, I do have friends, roommates and guests about now and again, so the issue is not completely in my hands. Hence, that's why I'm still keen to eliminate the issue. I think I can put together a concrete block solution - and will try that. Pity though - as the turntabe is so easily accessable on top of the rack, and looks great. Mmm, still the sound and concerns about cartridge outweigh the aesthetics and convenience factor, for me anyway. I'll keep you posted and will get photos up soon (camera still out of action just now - another story ;-) Thanks for advice on this one..
Yikes, mon, you're so keen on your nice TT on top of your sharp-looking rack, and you're going to try a concrete block solution? Whoa, keep your head! ;-> I don't want to push Neuance too hard, but given what you'd like to preserve, you might ask Ken Lyons if he thinks his Neuance would help your situation; he is not hype-ful. Save the concrete for if you really have to get serious.
Outlier- concrete blocks? Not sure they are heavy enough. You can try it. You can usually scavenge some bricks from leftovers at construction sites. They look better too. If you have space you can add mass to the rack. This is what most people do without even realizng it. You can use bags of lead shot. Cast iron weight plates are also useful. You know the ones weight lifters use on the end of a barbell. Smaller ones can be placed over the tansformers of your equipment to suck up stray magnetic fields.
I had the footfall problem with a non-suspended table in a livingroom system. Placing the table on a Symposium Ultra Platform which in turn was placed on Navcom pucks on the rack completely eliminated the problem without coloring the sound.
Your Symposium and Navcom solution should be a quite effective, albeit expensive, solution. Both have different compliances and would be attenuating different frequencies of vibration quite effectively.

I find the use of Symposium platforms, shelves, roller bearings, etc. extremely effective at dissipating unwanted vibrations. Great stuff.
