Graham Phantom Elite vs. AS Aquilar

I’m with lewm on this one. Way back when, I had an OL-modded Rega arm that set VTA with a grub screw on the shaft. I couldn’t run to a Graham 2.2 fast enough. VTA towers are a boon to sanity and civilization.

But the rotational stability of that Graham was indeed a detriment, one that the Phantom family’s magnetic stabilization largely, if not completely, overcame. Most other high-end unipivots have followed suit, including the pre-Tosca Durands and the Reed 3P, which is essentially a magnetically-stabilized unipivot, according to its lit. These arms perform a very high level using this "defective" bearing structure. But I do get mijo’s point, which is one reason I’m looking to go gimbal, or "gimbalesque," like the 4Points, with my next arm. I have a couple of gimbaled Ortofons (read, Jelcos) that perform surprisingly well but they are not in the league of my Phantom Supreme or III.

And I recognize the drawbacks of VTA towers. More superstructure to resonate, more mechanisms to introduce error and perhaps instability. What do you think of the Tosca’s innovative "spare-tire-jack" approach? Looks like either an ingenious solution or a big problem, I can’t tell which. I’d like to see one in action.

Durand Tosca

From my observation of a Tosca, it seemed to use an outrigger contraption, a metal peg that sticks out from the pivot point toward the spindle side.  That peg rides on a horizontal support strut set at a right angle to the peg, so as to keep the unipivot from rotating, at least to that one side.  I recall thinking that arrangement was not satisfying, given the cost factor of a Tosca.  The metal on metal contact would seem potentially to create noise AND drag on the horizontal travel of the arm wand. But perhaps my idea of what is going on is incorrect.

Lewm, I think you're thinking of the Telos, no longer made, which constrained the unipivot with that little bar, as you described. The Tosca is the newest Durand arm, and its first gimbal design. It has this unusual VTA adjustment that places the entire bearing assembly atop a kind of scissor jack. Weird but interesting.

Just wanted to bring this thread full circle. I ended up buying a new 10-in Phantom Elite at a good price from an authorized dealer, who had it in stock, amazingly. It arrives in a few days, and I’m excited. In the end, my addiction to Graham ergonomics was too hard to break. Best tonearm on the market? No. Best value? Hell no. But it will certainly be an upgrade to my Supreme and fit beautifully in the front position on my SP10R. Thanks again to all.
