I ordered two Mints from Yip way back in the day when I was using VPI decks. As Raul has noted, P-S was a critical measurement for Yip. He would not provide his custom protractor without it. He also needed to know the ID of the tonearm.
Now that said, is the Mint "pretty nice"? Well dayum, "pretty nice" describes a lot of things, even the mediocre. The Mint is very difficult for those with so-so vision or who have brains that for whatever neurological reason do not perceive paralax very well. And all for an alignment method that favors classical music with crescendos at the innermost grooves.
I’ve said this so many times that I am embarrassed to say it again. One can literally slam the cartridge to the very front of the head shell and if you nail the tracking force, VTA, and zenith you will get very good sound. With microline and similar stylii there is a fair bit to be gained by further optimization. The point of this is that minimizing arc-induced distortion is so incredibly overrated-it is like how you choose to set your broken watch so that at least it’s right two times a day.
