Sorry, I did have a FR64S, a win Lab SD10 and, for me the best arms, the Breuer Dynamic Type 8C, I had two, one black and one gold. I did have the opportunity to meet Erhard in Luzern when I was living in Wien. RIP.
The 9" Groovemaster II with sliding base and silver wiring is still available through Philip Holmes of Mockingbird Distribution for $1925, includes shipping and custom fees.
I have an interest, so try and stay away from too much subjective commentary. The Groovemaster is a great tonearm and good value. More balanced and controlled than the vintage FR64S, which for anyone considering a high mass arm should be a point of comparison. On the other hand not as 'exuberant' as the 64S either. I have both and love them for what they do well ( albeit differently ).
I've asked variations of this question over the years and never got a really straight answer. From what I could discern, it has a powerful, controlled sound but somewhat dark and rolled off top end. I remember when publication's did product comparisons but these single product reviews where everything is wonderful fail to enlighten.
I’ll bump the thread by adding a few objective details:
The current arm is the Groovemaster III
A mk2 arm can be upgraded to the new counterweight assembly ( and arm lift ) ~ $200
The effective mass of 22g is calculated using ( iirc ) 14g headshell. Or maybe it was 15g. At any rate lighter or heavier headshells can shift the effective mass value...
