The supplied cartridge is tracking around 3.5 gms, I agree, an AT Elliptical, tracking at 2 gm is smarter, however VM95e has only 20db of channel separation, 2.0db channel balance. The existing has 24db separation, and 1.5db channel balance, there is a chance it sounds better, i.e. more impressive than the VM95e.
This elliptical one has 27db separation, 1.5db channel balance, also tracks 2.0 gm

B&H, others sell it for $110.
They sell this protractor, and the other side is blank to set anti-skate

You mentioned Grado, this elliptical tracks at 1.8g and has channel separation of 25db, well worth the $125. IMO
Are you able to adjust the arm height? It is based on the height of the supplied AT3600 now.
