I've considered getting the Hana SL Mono MK II cartridge because both of my local dealers sell Hana and have recommended it. Just yesterday I sent them an email asking about their Shibata stylus. But now I'm just thinking about getting the Audiomods tonearm I've been wanting for the FrankenThorens that I've been building. That is, after I have all the panels replaced in one of my Quad 2905 ESL's. Those Quads are a pain.
Currently I'm using an AT 33 that I bought many years ago after Jonathan Carr of Lyra recommended it on one of my earliest posts about mono cartridges. https://forum.audiogon.com/discussions/which-mono-cartridge-at-around-1-300-00
The Miyajima would definitely be a game changer compared to what I've been using however the conical stylus would concern me slightly. For only $1,700.00 there's the EMT HMD 025 which I understand is a refined sounding cartridge but more reserved sounding than the Miyajima (just from what I've read). The diamond on the EMT is listed as an SPH 25, whatever that is. The magnet on the EMT is listed as an AINiCo,nickle-plated and the magnet listed on the Hana is listed as an Alnico.
Usually whenever I'm wanting to upgrade my stereo with a new purchase, I just look for quality and value and don't get too caught up in the integration of a specific tone. However that would change when it comes to phono cartridges and my understanding is that the Miyajima is the gold standard where tone is concerned. I primarily listen to classical LP's as that makes up the majority of my collection.
