Thanks, Pops, I'm certainly excited to say the least. Although it's definitely a grip of coin, I'm confident that it's the best next upgrade especially since I have a Basis turntable. I currently have an Audio Reasearch SP20 pre but will be moving to the Ref 10 soon.
Thanks, jwm - I know my question is rather subjective (like asking what cheese goes with this particular wine) since there are so many grand cartridge options out there these days. Hearing from folks that have the superarm 9 on a Basis turntable and hearing why helps me hone the thoughts a bit. Much appreciated.
