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.

Dear John: I'm wonder why you are walking when listening to your audio system.

Anyway, the MG-1 is not an Air Tangent and maybe your problem is a MG-1 problem. I can't be sure.

My advise: meet to a friend of you and test the MG-1 on his system and " see " what happen or try to get ( borrow ) another TT and test on your system.

Now, you have to take all those trouble only if the Mg-1 give you a better quality sound reproduction than your OL Silver.

Regards and enjoy the music.
Raul.

Low frequencies tend to collect in corners. A turntable mounted directly in a corner is subjected to mucho airborne vibrations. Not, as you already know, a good thing for analog playback.

You could try putting something designed to "absorb" mechanical energy (convert motion into heat) under the table, such as a Nuance or Symposium shelf. If the floor vibration from walking is a very sharp impulse, but not a very large up and down vertical movement, a shelf might attenuate the impulse enough to prevent the skipping.

Good luck.

Oz that is true if the turntable is is put in a corner in the direct line of the loudspeakers. I guess it was not clear, I suggested a different room. Mine is located around the corner behind the speakers.I guess that causes problems too. Like long cable runs and makes adjusting vta even more of bitch. I guess that's why this hobby is so much fun.
