Benz Ace S H or Dyna DV-20x2H

The carts are pretty comparable in terms of weight, compliance, and tracking ability (neither is a great tracker). There should be no compatibility problem with your arm.

Overall, I find the voicing of the Benz, with it's vibrant midrange, to be more fun, but ultimately prefer a more neutral midrange. (I should mention that I have the low output Dyna, not the high). I haven't tried any other high output carts in that price range.

Have you considered any low output MCs? I think they are preferable to the high output versions in most cases. It looks like the Phenomena II should be able to handle low output carts.

Low output being better sounding in general than high output MCs is just something that seems to be a consensus that I've picked up from reading various forums (I've only had a couple high output MCs, the other being a Dyna 10x5). Not sure how serious that should be taken.

I'm surprised 60dB was not enough gain for the AT33EV as that's the gain setting I use for my AT33PTG, but this is probably pre-amp/amp dependent.

To answer the tracking question, in my limited experience, price has little to do with tracking ability. One of my best trackers is the AT150. The AT33PTG tracks just as well as that one. The Benz Ace and Benz Wood track about the same as eachother, only OK compared to the ATs. If I recall correctly, the Dyna 20xl may have done a little better than the Benzes. This is with the SME 309 arm. Tracking was tested with the Hi-Fi News test record, but also by listening to inner groove performance with complex symphonic music. Now this may only be the case with the SME, but I think the point still stands about price vs. tracking ability.

Good to hear about the Ace tracking and stylus improvements. Mine is an older Ace.
