Not exactly dragged in; after all, the OP asked if his money might not be better spent on "a new, modern cartridge with a stylus," and who better to go to for information than Shure themselves?
Great description!
Nice post. This is the kind of feedback that helps people make choices. I'm sure you will report back if you try a new stylus on your M97xE, and it sounds like the OP is leaning toward trying a stylus or two for his V15 IV. Nobody has chimed in yet with PS-T2 experience, so whatever 6BQ5 discovers might help someone else with the same model.
There was a short thread a few months ago in which someone asked if the particular turntable to be used made much difference in cartridge selection, and I think most agree that it does. The M97xE, to my ears, has been a completely satisfying cartridge in both an LP12/Ittok setup as well as my current Rega RP3. As previously noted, it was not my favorite in either a Denon or a Well Tempered model. Much of the positive comment on it I've seen in this forum has come from Rega owners, and the reasonably positive review in TNT Audio used a Rega RB300 arm in a Michell GyroDec, where, unlike your experience in the TD 160, they noted, "The midrange and treble areas lack some air and definition, but the '97 somehow avoids sounding dull and boring. If anything, the music bursts forth with quite some enthusiasm." In my setup (RP3 with Audio by Van Alstine preamp), the M97xE gives me all I could hope for in terms of pace, rhythmic expression, and dynamics, along with a completely natural-sounding tonal balance that never calls attention to itself. I never even think about recording quality--I'm just swept away by the musical performance itself--but I know not everyone has this same experience with the M97xE.
