What are those audible problems? I asked earlier and you apparently thought I was being argumentative. I wasn't, it was simply a serious question. I'd like to know what the aural/audible manifestations of the phase shift you're talking about are.
Follow Ups:
Phase shift is a time distortion and it varies with frequency. In this case the distortion is plus. As it's plotted, it peaks at high frequency resonance where the shift approaches 180°. The shift diminishes on either side of that peak and will eventually go to zero.
Ortofon used their MC200 as an example, saying that undamped it had spectacular imaging, but was unlistenable due to excessive brightness. Damping was required and imaging suffered the more damping was applied.
This analysis is looked on with some suspicion. It could be the rising amplitude response that caused the spectacular imaging or a combination of those two. Imaging is the only aspect of performance alluded to.

I don't hear timing issues with my mm's, all of which have pretty good imaging. I'm more concerned about realistic timbre anyway, and if there's an effect on timbre due to phase issues that my carts have I'm not hearing it. 'Course my whole system is far from SOTA.

I'm keeping it secret. The only way you'll ever know is to make your own comparison.
Good Riddance,
