ELP laser turntable - any comments?

Useridchallenged, I think this is the sophisticated controlled spring isolation base. Versus the acoustic feedback unit as the Stereophile show. It was from Halcyonics. Do you know if this is correct?

The Minus K products are based on their patented Negative Stiffness Technology. From a physics point of view, the spring equation is F = k * x, where k is the "spring constant" or "stiffness". Minus K gets their name because they have found a way to implement "negative stiffness" or "minus k" if you will. So, yes, the Minus K system is based on a sophisticated mechanism that includes springs.

I know little about Halcyonics except that it is an active isolator (hence it requires feedback). I just went to the Halcyonics website, and checked their specs, and Minus K still outperforms.

The Minus K set-up is pretty easy, you just dial in the payload (literally, there is a knob and a payload balance indicator), and you're done. It looks like the Halcyonics requires software and other tweaking to make it work.

Albertporter - does the weight of the Walker include the air isolator? Or is the 400 lbs just the platter/bearings/plinth/tonearm/motor? If you replace the air isolator with the Minus K isolator, you will probably strip out a lot of weight (and wires, and pneumatics) and probably save some space, too. I would imagine that the Walker platter/bearings/plinth/tonearm/motor would be well under 200 lbs. I know that my Yorke is about 75 lbs, which includes a 25 lb platter - all the rest is bearings/motor/plinth.

Useridchallenged...The Halcyonics table is completely self-contained and easy to use. Just adjust (knob) for the load weight (as indicated by a LED). At work it performed flawlessly in a critical optical task. (Eliminated ripples in a pool of Mercury).

Userchallenged,

The Walker isolators contribute the least amount of weight in this set up, just a few pounds for sausage sized PVC tank, some hoses and three pods. Holding them in my hands last year, I would guess the whole thing at 20 pounds.

The Walker base is probably 200 pounds and the platter is 75 pounds. Then there's the air bearing, tonearm, motor, motor controller and the platform.

I tried to get Lloyd on the phone for an accurate answer, but since he just returned from vacation (7K miles on a motorcycle !)he's been swamped.
