Tonearm mounting differences Graham vs.Tri-Planar.


I would appreciate for explaining mounting differences Graham vs. Tri-Planar.
Is the high is the same for both?

In other words if I can place them on the same arm board (plinth) and only mounting holes drilling pattern would be different, the high would be the same, not requiring any high adapters, transition panels?

Dougdeacon and Syntax,
Thank you so much for your advice. Now is clear, I will keep the same arm board and re-drill it for the Tri-Planar.
Now I need to find one somewhere.

Dougdeacon, based on your previous post and experience, would you confirm that for ZYX Airy 3 cartridge the Tri-Planar would be one of the best options among others.
One of the best? At its price point I'd say yes.

Syntax has compared Tri-P vs. Graham Phantom using a UNIverse. I believe he prefers the Phantom with that cartridge. That's a bit costlier though, as you have to buy a tonearm cable.

Schroeder arms are also good with Airy 3. Softer bass than a Tri-P but quiet and with a low sound floor, which helps the Airy 3. It's a lively cartridge and likes a quiet arm.

The Durand Talea is the best tonearm I've personally heard (with ZYX UNIverse or Ortofon A-90). I've no doubt it would be exceptional with an Airy 3 also, it's the quietest tonearm I've never heard but sacrifices nothing in terms of solidity. Quite a bit costlier than Tri-P however.
Dougdeacon, thanks for sharing your experience.
The Talea and Syntax a bit too pricy.
What other tonearm options for Airy 3 would you recomend, in a range of $2k-$3k?
Quite a bit costlier than Tri-P however.

The Triplanar has considerably harder bearings (hardest made anywhere in the world) and are thus the most durable; also having the least friction. However its not a $2K-$3K contender unless you find one used.

My findings are different from Doug's; IMO (using recordings I have recorded and released on LP as reference), the Triplanar is the more neutral arm for less money.
