How quiet it runs in the groove is quite important to me - I've got a lot of used records in less than perfect shape. Inner groove distortion is a big no-no in my camp too. The Exact I'm running now displays no inner-groove distortion but isn't the quietest on some used records.
My musical preference is primarily classic rock - so dynamics are a big deal to me. If it's any indication - I actually like the Rega Exact MM (quite a bit too...) and the Goldring 1042 if that gives you an idea of where I'm coming from.
I've considered the Denon carts - but the AT is higher output at .4mv and tracks at a lower VTF. Everything I've read is that the sound from either is great - so the OC9 sounds like the winner to me.
Any comments with regard to noise, dynamics, and inner-groove distortion (tracking) and the OC9 would be great!
I'm not sure that I do need a spacer Jphii - I just thought that I might in order to get VTA correct. I've got some 2mm spacers coming from Red Trumpet though so I'll have them if need be.
