BEST TONEARM FOR HIGH COMPLIANCE MM

I am using a Signet XK50 with the Soundsmith Aida High Compliance Cartridge. The Signet was one of if not the first to use the counterweight so that it was on line with the stylus thus providing even and constant downward stylus pressure on the varying surfaces of vinyl. The cartridge tracks at 1 gram.

SME III w/ hyper stiff titanium-nitride very low arm mass of 5 g fits the fuzziest MMs, w or w/o fluid damping. This arm gets the best out of SHURE´s top dogs, and likely all other top MMs. Reasonable price. Looks very beautiful too.

State of the Art.

If a high compliance MM or MI cartridge was in my future, I would not hesitate to go the SME 3012 route.  I had good results (back in the day) using a Grace 707, but there's no comparison to the SME 3012.

Dear lohanimal: In the past that kind of tonearms was the " fashion " nothing more than that. Please don't worry of what people said in those very old times.

Yor cartridge is around 30 cu ( tyhe same as the Stanton similar model. ) and remember that comes with that damped brush. 

What tyou have to look for is a well damped tonearm and that's all. If you want a vintage one you can't find nothing better than the Technics EPA 100 or the Lustre GST-801 where in both cases your cartridge will shines!

Regards and enjoy the music,

Isn't the cartridge called "XSV4500", not "4000"?  If not, then I have learned something new.  Never heard of the 4000.  You've received several excellent replies to your question; I think they're all good ideas. To add to the data set on the Unitrac, this is also one of Win Tinnon's favorite tonearms.  But what strikes me is that if you own a Moerch, can't you get a second arm tube for it that is medium or low mass, and just go with that?  Might save money and the aggravation of mounting a second tonearm.  And the DP6 with a medium to low mass arm tube will likely be at least the equal of anything else mentioned.
