That is good to know on the Miyajima .7 Tom. I am a bit envious of your stable of mono cartridges
It seems that, even more so than with stereo cartridges, it pays to have a variety of different mono cartridges for the different mono eras (excluding 78's of course which require an entirely different non-compatible animal). For the guy (like me) who's looking to do all mono with one cartridge it's a little bit daunting and probably fraught with compromise.
In that vein, I'm curious to know, having owned the Dorian mono, what your thoughts are with respect to the line contact stylus it had on it? I know it's an apples vs oranges comparison with the Dorian and the Miyajimas but am wondering if you feel you are giving anything up in the way of detail retrieval or high frequency tracking/performance with either vintage monos or reissues with the conical styli on the Miyajimas vs. the LC on the Dorian.
Based on fairly extensive experience over the years running heavily modified Denon 103Rs (with improved bodies, cantilevers and line contact styli), along with the fact that both Ortofon and Lyra (and Koetsu I believe) seem to be pretty content with putting line contact styli on some of their pretty upmarket mono cartridges, I was actually leaning toward a retip of either the AT 3 I currently have or possibly an AT 33 in the future with something like a boron or sapphire cantilever and LC or Microridge stylus.
With the 103R and stereo playback, I could never have gone back to the stock conical as it was just missing too much information and a bit crude in the high frequencies when compared to better stylus profiles but I have to admit that I'm a bit uncertain that would be or is the case with mono playback and am rethinking the issue after using the AT 3 with an obviously modest bonded conical with such good results on both older and newer monos.
