There was a review of the ZYX RS30 in an english mag (HI-FI+) a year or two ago. They didn't like it much (if I remember correctly, they said it had a warmish, coloured sound, and not enough PRaT). In the same review they reviewed another ZYX (either the R100 or one of the R1000's) which they liked (actually, they really seemed to admire more than like its transparency/delicacy), and the Benz Micro Ace, which they seemed to like more than either ZYX(!).
Guess they like the Benz sound.
I have owned at least 10 Monster Cable Alpha Genesis 1000's over the years (they were made by Nakatsuka, head man at ZYX). It was (is) a very even-handed, pure-sounding cart. It is only average in PRaT, so if that is your thing, you would not like it. The folks at ZYX say the ZYX R100 is practically the same cart.
