Hi Larry,
Was this a session where Frank set everything up?
The reason I ask is that you can exercise in enormous amount of control in how much energy you release into the tonearm based on how tight the cartridge screws are. This can have a dramatic effect on both dynamics as well as a perception of brightness, and tighter isn't always better. You need to experiment with each arm/cartridge combination.
We're talking about minute changes - 1/32 of a turn of the cartridge screw. If you were unaware of this cartridge bolt torque parameter, you'd never guess that your setup was suboptimal. It was at the feet of Herr Schröder that I learned this only last year. Please take this comment in the spirit in which it is offered.
Now, if one were to lay out a hierarchy of brightness (an orientation toward the upper frequencies), then the Graham 2.2 would be the brightest of the three tonearms. I don't think anyone on this list would disagree with this statement.
Certainly, the Universe is a more refined cartridge than the Airy-3, exactly in the areas you report. Any of these weaknesses would then be exacerbated in the Graham - especially if it were suboptmially mounted.
I don't think that this is a gimbal vs. unipivot issue, but rather an expression of three different designers' aesthetics.
As I've written before, I have an immense respect for Bob Graham, even though I've been beaten up on this forum in the manner in which I expressed it. Bob knows what he's after and achieves it. His gimbaled bearing Robin sounds very much like his 2.2 - achieving 90% of its performance (when you swap out the arm cable) at 1/6 the price. I've heard that he's made great leaps with the Phantom and am certainly interested in hearing if first hand - of course, in a world-class turntable like a Galibier .
Cheers,
Thom @ Galibier
