seek mc cart recommendation for Townshend Rock III

I'd be very grateful for advice: I have come into a small windfall of cash and am looking for a mc cart for the Rock III, with damping trough at the headshell end of a Rega RB-300, into a Heed Quasar phono pre (system details below). I am currently using a Grado Ref Sonata and would like to retain some warmth and especially natural musical timbre but improve detail retrieval and especially tracking. I have about 3000 albums, mostly aquired used, so I want a cart that is very quiet in the groove. I listen to all types of music except classical and opera, but especially 50s & 60s jazz, 60s-70s rock, and some folk.

I am considering the following but because of location will have no chance to audition any:

EMT TSD-15
Ortofon Cadenza Bronze
Dynavector XX2-mk ii
Benz Wood SL or SM (or even the Ref Silver or Copper)
AT33EV (I know this is in a lower league, but I hear it is very good)

A longtime Rock user tells me it works very well with carts with line-contact styli.

I would be grateful to hear whether the Ortofon would be too dry, after listening to the Sonata for years, and whether the AT33EV would sacrifice a lot in comparison to the others. Also, am I missing any obvious choices in this price range?

Thank you in advance!
