Hey Jim,
I work for Ortofon, so maybe I can shed some light on your question.
The 2M Bronze is designed for all medium-mass arms.
Compliance, while a meaningful figure, is always examined within the context of the cartridge weight.
Since the 2M Bronze is 7.2 grams versus the Concept MM at 10 grams, you would still maintain great compatibility with the Concept arm despite the compliance being different.
As far as the Geodisc is concerned... That's what I use! But any Baerwald-based alignment tool would be equally good. Geodisc is a bit quicker to use than a standard 2-point protractor, which is why I like it.
Any other questions, you can find our email addresses and contact details at www.Ortofon.us. We're always happy to help.
