Both my experience reported here and the findings reported in the Stanton TT setup thread suggest that the idea that mistracking an LP once produces mistracking on subsequent plays, regardless of the current setup, may be largely a myth.
This was even more worrying as no aftermarket stylus has appeared for the V15V.
surely it is the cartridge more than the stylus that is responsible for the strength of the cartridge output, no?
By the way, according to a Shure support person, the M97xE stylus will only fit the V15VxMR cartridge, not any other version of the V15V. She also said Shure has never tried the stylus in the cartridge and so knows nothing about how it might work or not work, only that it will fit.
So, the vague thought rattling around in my head: that tonearm’s gauge will not be effected by the bias setting but perhaps the final reading on the stylus force gauge is some summing of the two, tracking force and bias.
Ultimately I'd take the reading from a decent stylus pressure guage over what the arm's readout says.
Since only the right channel has mistracking in all three instances, I would guess some cartridge alignment problem.
Bias seems optimum. Turning it either up or down only seems to make things worse. With the bias adjustment set, the right channel mistaking on the inner and outer tracks of side 2 is very small. Changing the bias either way seems to make it worse. Only the +18dB track has very much mistaking. Even if this track can be improved by some more extreme bias setting, it does not seem worthwhile to lose the quality on the more normal tracks.Since all the mistracking I see is in the right channel, regardless of bias setting, alignment seems like the more likely cause. There is a gauge of sorts (the alignment protractor, in several variants) to use for overhang, but most of the adjustments are mainly by eyeball. Many tonearms, like mine, don’t have adjustments for azimuth or vertical tracking angle.
In theory! Maybe with access to micro vascular surgery instruments and nano production tools, and maybe a stabilizing force field that can keep things absolutely stable while rotating the entire setup to angle where one actually has a clear line of sight to the stylus/cantilever interface so that one could make a useful assessment of the effect of the changes one is attempting to implement. Otherwise just getting the bolts through the cartridge shell, getting the nuts onto the bolts, getting this setup into some alignment that seems like it might relate to the gauge, then tightening it into the alignment you’ve spent so much time obtaining, without the tightening operation markedly altering the alignment -- even without additional tiny skittering add-on parts in the mix -- is a tremendous pita. And this is assuming, which seems like a very remote possibility indeed, that one could actually find some shims that are the right size and thickness.
