Hi Brad: The G7 is a much newer model than the APM-1. Also, the APM-1 was made under Arnie Nudell's belt before the company switched hands. I really have nothing to offer as far as comments on the newer stuff because I've never heard any of it. From what I understand though, the APM-1 was not a design that the new Genesis carried over. Let me know if you ever make it to Genesis and if you get to hear their newer stuff.
Good luck!
