I hate to sound like a broken record, but I have an SME/30 and an SME IV.vi arm. I tried a Van den Hul Colibri, a Clearaudio Insider and a Shelter 901 (best of the bunch) but it was the Dynavector XV-1s that had the magic. In MY system it thoroughly bettered the VdH and Clearaudio each of which were MUCH more costly. I also agree with Raul, the Shelter 90X would be my next choice. The 901 is very nice too but if you can swing the extra $$ for the Dyna, I don't think you will be disappointed - it is very balanced from top to bottom, has excellent punch, great harmonic texture and loads of detail without glare or fatigue.
Just my $.02
