@nandric Dear chakster, I own both; JVC-X1, mk1 as well mk2 . Both
have solid beryllium cantilever + shibata stylus. If titanium
cantilevers are available than as separate styli. There are also
aluminum kinds available for both X-1,mk 1 and mk 2.
What’s the point? You don’t have the model i am talking about, this model is
X-1IIE and it comes with
Titanium Cantilever (tapered pipe), the stylus replacement part is orange. The models you’re talking about are all have
Beryllium Cantilevers (solid rod) and they are completely different (with clear stylus replacement part). I hope you can see them all on my pictures above.
The rest of what you’re talking about are made by JICO, because JVC/Victor never ever made those top models with aluminum cantilevers. JICO made modern replacement for them, they are also orange in color, but does not have tention wire, they are not even SAS and very bad quality compared to the original Beryllium or Titanium.
P.S. X-1, X1II, X-1IIe cartridges killing the Grace F9 series with ease, they are superior and belongs to the best MM ever (they are also much lower in compliance which is no problem to use on any modern tonearm).
