Graham Phantom Supreme?


Has anyone done a comparison between the Supreme and the mkII? Is it worth changing and expending the extra outlay?

The main revisions appear to be the bearing housing and an improved magneglide stabiliser (I think the internal wiring was up to a good standard already on the mkII)

There is a company called AudioMax Ltd (approved contractor?) which can perform upgrades from both Phantom I and Phantom II to the Supreme build.
Any experience of this conversion out there ?
Many thanks... :)

Dertonarm: "As I said: look careful to the off-set of the headshell mounting area. It is correct only for the original 9" version."

I think what you meant is that the offset angle at the BEARING was originally designed for a 9" armwand. Matching bearing angle to headshell offset angle is to avoid VTA affecting azimuth. I assume the Supreme's bearing was angled at 23.431°, according to spec, to match 9" wand's headshell angle. I can't imagine they would make three different bearing housings for each wand length. It's probably too minute to bother most buyers but perhaps not a perfectionist like Dertonarm. :)

Dertonarm: "In an uni-pivot like the Phantom the bearing has no off-set - just the mounting area has."

Actually there is an offset angle at the bearing with semi-unipivot designs like Phantom (or Basis Vector, Continuum Cobra/Copperhead, etc.. in the same genre) because there's a secondary bearing to stabilize azimuth so if you draw a line between the main bearing and the secondary bearing, it is offset at an angle matching exactly like the headshell. This clever design allows the azimuth adjustment having no effect on VTA. Same concept in many fixed bearing designs.

A true unipivot like the earlier Graham arms, such as 2.2, used offset angled outrigger weights to do the same thing, and since Graham has a patent on this feature, you don't see other arms doing that.

Anyway, thanks for explaining about the Supreme headshell issue.

That Bob Graham quote does not prove anything in this context because he did not say he compared the standard connection to a single set of wires to the preamp. The jury is still out there, I have to say.

P.S. He's a manufacturer. Of course he wants his product to be flexible. I don't blame him.
