Retipping Miyajima mono cartridge

Has anyone had their Miyajima Premium mono cartridge retipped by Soundsmith to either elliptical or line contact, if so did it change the overall sound quality?

I can't say I am a fan of the rather crude conical stylus being played on some of my vintage mono LPs some of which are $1000+ each.

Probably of no concern to the OP but a line contact stylus can damage records pressed on styrene. Many mono LPs and 45s from the 50s and 60s are styrene.
I would rather have an "all rounder" conical, personally.
I can't see why a conical profile would have any difference in life span versus other profiles. But they are any number of variables involved. Poor set-up, improper cleaning and care, dirty records, cheap stylus, etc. Any of these things will greatly reduce stylus life from the ideal.

My experience with stylus life, no matter the profile, is they last far longer than is commonly reported. Things do wear and change but the most important factor is has the stylus worn enough to cause permanent damage to the record?

Some people will tell you a stylus is shot at 1,000 hours or less. I routinely run my cartridges well beyond 1,000 hours with no damage to my vinyl. I keep my records and stylus clean but I am not fanatical on this point.

The best person to ask is the importer for Miyajima. A great guy, a wealth of knowledge concerning all things analog and he will give you the straight story. He is far more interested in a satisfied customer than selling a cartridge, or re-tipping, before it is required.
Andy Chong of Cartridge Clinic is rather a contraversial decision to take your cart to. Although many have said good things I know for a fact he doesn't often repair the carts himself but rather ships them to China to one of his repairers.
How do I know this, I sent my Clearaudio Insider because the cantilever snapped off and he said he could fix it when even Clearaudio didnt want to do it. So 3 weeks later and no cart I pressed him for some details of when it was going to be done. He was stalling and couldnt say exactly when so I did a suprise visit to the shop and demanded to see my cart, guess what... he couldn't because it was in China!!!! He didn't tell me until I wore him out asking where it was. Unbelieveable!!
So two weeks later I get it and install it on my table, the cart was totally unbalanced in volume and grainy sounding. Tries and tried slight changes but it was obvious the cart was just F$%^&*d. So I call him up and explain how it is, he says a lot of BS and offers me $100 off the $900 bill and to take go elsewhere if I don't like it!
Stay away from that shop!!!!
