I am using a Benz Glider LO, paired with EAR 834P. I think it sounds great, a big improvement over the Eroica HO. Surface noise was reduced and the sound is more lively and better bass. I have since tried the Eroica on another arm/table and finally came to the conclusion that I just am not excited by that cartridge. I also use an anniversary ringmat, a speedbox MKII (highly recommended, if only for the convenience of switching speeds--it makes you more eager to purchase those 45 rpm audiophile recordings), and no record clamp.
I raised the whole turntable up on isolation cones:

The MMF-7 sounds great!
I leave the dustcover on (but raised while playing) because I could never detect a difference with it off. Perhaps this is because the table is installed on a recessed shelf and not prone to so much feedback from speakers.
