Help deciding which TT

A little background.

I currently have a Rega RP1 w/Ortofon 2M Blue. It seemed great until I added a subwoofer. The sub is exhibiting woofer pumping when attempting to play vinyl. The problem even occurs if I place the needle on a record without the motor running, and then increase the volume. As the volume increases (again, the patter is not moving), the subwoofer (Martin Logan Grotto I) will start to pump. Eventually the sound becomes audible.

That IMO eliminated any motor, or bearing issues.

I've moved my TT to a wall shelf which seemed to have greatly reduced the pumping, but it's still present. I'm at the point where I'm thinking about purchasing a higher quality table. Here are some options I'm considering.

1) Brand new Clearaudio Concept w/ Clearaudio MM $1600
2) Demo Rega RP6 w/Exact Cart (full warranty) $1500
3) Lightly Use VPI Scout JR w/Ortofon 2M Black $1300
4) Used VPI Traveler V2 w/2M Black (200 hrs) $1000

I understand that I may have still have the same issue, but I'm hoping a better table will reduce/eliminate the issue. Any thoughts on the above tables?

Thanks

You moved the T/T while the stylus was down on a stationary platter? Danger Will Robinson!! ;^)
Your wife should have warned you to tape the platter first before engaging in these shenanigans ;^)
You need a personal Force-Field to prevent you accessing your turntable. :)

Joking aside, not exactly air. It was supported by you while your feet were on the floor. Effectively 2 forms of support in parallel, you plus the rubber feet on the maple block, one(you) more massive than the other.
In theory this should have been worse!
I'm wondering if your stylus bounced up in the air slightly while you were lifting????

Between the table combos listed I would prefer the scout.

If you want to buy a new TT, by all means get one. But you shouldn't be forced to get one over an issue like you are having. If you try some different settings on you sub (including not using the LFE connections at all), and some isolation devices, you should be able to get everything working.

"As I said above, bicycle inner tube. But you seem to prefer anti-gravity guns and new turntables."

I'm willing to give an inner tube a shot. I did try some packing air pockets under each of the three feet, and it really didn't seem to make much difference. They are the things that they use in shipping instead of packing peanuts.

Would a 12" diameter work? The RP1 has a footprint of 17.5x15. I can also get a 14" tube as well.
