Oddly enough, my interactions with Andy, which have not been extensive, have been very pleasant and professional. Perhaps he's worked on his "bed side manner". Yes, they're not exactly the same stock, but darn close and yes, its not a shibata but a linear contact stylus but my listening/measurements are very similar to a stock Miyajima with the cantilever resonance/amplitude being in the same place, more or less, and with the same amplitude, and the alignment of the device is spot on so he managed to put it together without disturbing the damping elements or the coils, which is not an easy thing to do. The Shilabe has a pronounced cantilever resonance peak in the high sonic/low ultrasonic range, the Kansui is much less pronounced, and the Madake is between the two- although my second device measures/sounds peakier than the first. These choices were made by Miyajima-san and help "tailor" the sound of his cartridges.
So, if you don't want to cough up the big bucks for at least the Shilabe, and I would expect the Kansui too, Andy does a fine job.
