I have a 40A that I'm running with a Realistic R47ED (Shure M75) and a Pfansteihl 4760-D6 conical at 3gr. I have to say, it is the best combo yet. I've run an AT10 conical that was meh. The EVG 4760 DE was sibilant so I moved it to a Technics SL-1900 where it is not sibilant. That cheap Pfansteihl sounds the best, tracks well, and opened up the soundstage dramatically. I know a lot of people like to bash them, but it is a damn good sounding stylus.
Edit: I will add that I like running conicals on my changers now as they are less fussy with alignment. Also, I'm not sure if it is true if all Miracords, but my 40A likes to destroy styli. You have to be really careful when manually cueing or just being in the vicinity of an unlocked tonearm. If you aren't careful, the tonearm will leap toward the spindle, crashing into any record or mat on the platter. I've done it a few times and refuse to run a stylus that costs any money, YMMV.
