To Perfectionist: I just got a Technics SL1210 M5G (Grandmaster), and also got a Shure M97xE because of all the buzz. I also had an Ortofon OMP 10 lying around, so got a second headshell and 1/2" cart adapter. I much prefer the Ortofon. It has about as much slam, but is smoother through the midrange, has more inner detail, and just "feels" better when I listen with it. The Shure by comparison gets congested and hollow-sounding in the midrange when things get busy (i.e., crescendos bringing in lots of instruments/voices).
Also, this humble rig has had no trouble smoking the CD/SACD players I have in the house. It's certainly as dynamic, bass is fuller, and the timbres are much better fleshed out. I have an Amber 17 preamp, and maybe it's spoiling me. If you're plugging into a phono section in a receiver, that may be why you're underwhelmed.
Also, experiment with the Shure--try it with the damper brush up and down, and with different tracking forces. I also tried it with both the extra headshell weight and the extra tonearm counterweight to increase tonearm mass. That seemed to open up some detail, but I still prefer the Ortofon w/o the extra weight.
