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.

If it doesn't happen with your other arm, then there is something with the MG-1 which is different.

Perhaps you have the tracking force set a bit too light?

Perhaps the arm bearing is not quite level?

Air pressure not right?

Check your set up.

Air bearing arms are notorious for difficult set up and maintenance. You might just have to get used to playing around until you get it where you want it.

The more spongy crap you put under it, the worse it is going to be.

Gregadd, suspensions often do not fix the "bouncing" issue, but often make it worse.

My Linn LP12 that I had for years, always had a very noticeable "bouncing" when I walked around the room.(Yes, it was set-up correctly).
My unsuspended table never had any problems like that.
