Graham Phantom Supreme?

Dear Lewm, dear Rockitman, - I can't resist, but I now have to second Syntax' choice for the 9" arm wand. While I am certainly usually try to go for increased effective length, the 9" standard arm wand is the best for the Graham Phantom.
Why ?
I leave this to Syntax to explain - as it was on his selection of all 3 arm wands that it was discovered.

The 10" arm for the Graham is the way to go. That was Musical Surrounding recommendation anyway.

Did they say why?

The longer arm having more mass also increases inertial mass of the cart which can be problematic depending on the cart used. Longer arm tubes also allow for more resonance. Bob Graham said this to Musical Surrounding and believes the 10" is better overall than the 12" even though you will have slightly lower tracking error with the 12". That's how I understand things anyway.

Dertonearm. the 10" arm is the sweet spot according to Graham. Lower tracking error than the 9", but less effective inertial mass than the 12" which can be good depending on the cart.

Rockitman, I usually always would go for lowest tracking error - i.e. 12" effective length or more - even at the sacrifice of increased effective mass.
But with the Graham Phantom this is a different issue and the 9" is the "best" arm wand out of the 3 length available.
Syntax may have the honor to reveal why.

I think, Musical Surroundings has (or the person behind it) a problem to listen and to understand something right. Nothing unusual in that business btw. And Graham never said or wrote anything like that, because this isn't his opinion.

You very well could be right. They chose the 10" to show off the Clearaudio Master Innovation, which I have on order. The best part of the Graham...I can buy all three lengths of the arm and decide for myself. What length are you using ? I'm using the 10" right now on my Clearaudio Innovation Compact. Fantastic arm.
