Stepping up to Air Line Arm?

And, what about bass 'thwack'?

Thanks for the comments so far. Sorry to push a hot button on the bass issue SirSpeedy. No agenda here, just plain ignorance. :)

One other issue I am facing with the bigger Kuzma table is physical isolation. The Kuzma Reference is pretty good on its own, given that it has a suspension. The XL does not, and unfortunately, my listening room, for now, is at the top of the house, and has a wooden floor. I could go the route of a heavy duty stand- eg Finite Elemente makes one perfect for the XL- but i'm still not sure if it is set up on a wooden floor -covered by wall to wall no less (yeah, I know, but the house has been an ongoing project and you'd be impressed with what we've done so far- the original rooms date to 1790).
So, what if I put a massive piece of granite on the floor, and then mounted a heavy duty stand with isolating stuff on top of that foundation?

OK, here's my compromise right now, with the concerns some of you expressed clearly in the forefront of my mind. The folks at finite elemente were kind enough to credit me what I paid for the Master Reference wall shelf toward the heavy duty (rated 120 kg) set up that is a low floor stand with a bottom shelf for bracing and the top for the TT. I will spike it. It is pretty massive itself, and with the XL on top, will be quite heavy. Although the Stabi Ref is a suspended design, I have temporarily been using it on an old target floor stand (while awaiting delivery of the now aborted Elemente Wall Shelf) with nary a problem.
The floors in the room are relatively new- since the entire top floor of the house, including joists and flooring, was rebuilt by the prior owner about 5 years ago.

If there is a problem, I'm told that the HRS isolation platform could be used on top of the finite elemente stand- even though that sounds like it might be overkill. So, for now, I'm gonna try the finite elemente stand, straight up.
I am reconfiguring the room as well, in a way which will allow me to install the compressor for the Air Line arm in an adjacent closet, and run the hose through a small cut-out in the wall.

I have also found an old brass surgical lamp- like the ancestor of the thing you see at dentist's offices- which has been rewired and will be mounted above the turntable for light, and for drama. I am excited. I should receive the TT Saturday, the stand late next week, and in the meantime, my electrician has just installed a new subpanel, all the way 'upstream' with Square D breakers, and will route 3 dedicated lines to the new area in the room where the equipment will be installed. I should be in business in about a week to 10 days and will report then. You guys are great. Thanks for your feedback.

EBarker- I saw the pictures on the 6moons site of their visit to Definitive UK, and sent Definitive an email inquiring about the source of the wall rack, which looked like a simple affair. Unfortunately, I'm not sure I have a brick wall in the room to support such a rack.

Hey, if it doesn't work, one of you might want to buy an finite elemente floor stand, almost untouched by human hands? :)
