Kuzma 4Point Tri-Planar

That is one strange looking counterweight. It seems as though they are not only getting the center mass of the counterweight below the pivot point, but also putting it as close to the pivot point as possible, even next to it so to speak. That would certainly make the arm more able to react quickly, having that mass on the pivot point.

Ptmconsulting, you're right and I think that is the intent of the design. Now, that certainly is a little different in the counterweight of the Durand Telos, isn't it?

Dear Hiho, I will give the Spiral Groove a good look.
On the other hand I will join the ever growing group of tonearm designers very soon.
Thus I will not comment on any other tonearm design - especially not current/new models introduced only recently.
My statement regarding pivot tonearm will be introduced here on Audiogon later this winter.
I will rather let facts speak for me - same as I did regarding tonearm alignment.

Unoear,

thanks for the heads up.

alas; i now only have 1 turntable with spots for only 2 arms....and both spots are taken. but if i get a chance to investigate a Phantom II Supreme i'll check it out.

Daer Syntax, if you hear and care to comment on sonic differences between different lenghts Grahams it would be greatly appreciated! :)

Oscilloscopium, your comment is particularly interesting to me, because I found I prefer my Omega on the T-P (VII though) and since I put it there I haven't bothered to experiment. I'll have to mount it on the Reed 2A and see how I like it now after I've lived with the T-P for some time. T-P does track it better and it sounds more weightier though.
