stone1,
The 103R is a good all around performer that isn't really fussy about what arm you use, as long as it has enough effective mass. As stated above, it was mostly insensitive to the azimuth control issues of the WT arm, so it sounded very consistent from needle drop to last groove. I had better cartridges but they had stylus profiles that sounded better with rigid bearings. Also, my experience was high compliance cartridges didn't work well because even with the paddle mostly out of the silicone, the arm seemed over damped. That wasn't a problem with medium to low compliance carts.
