The 13D was made for US market only, it was a special development of the 17D according to the interview with its designer (Tominari-San):
" At first when I tried short cantilevers I worked in sapphire or ruby and their resonance dictates a length of 2.5mm. But in Diamond, it is possible to use 1.7mm. We even made a very special product for the US high end market with a cantilever only 1.3mm long, and called the Karat 13D. It was our flagship model and sold nearly 60 pieces in America. The 17D was the first diamond cantilevered cartridge that we made, and the 13D was a very special development of it, using a special body and headshell arrangement. " - Dr. Tominari (Dynavector Systems)
Dyna cartridges such as XX1 (first) with Flux-Damper and later all Dynavectors cartridges "involves winding a wire around the front yoke of the cartridge. Experiments showed that movement of the coils was generating a voltage in the yoke which in turn effects the linearity of the magnetic flux. It is this that makes many poor movingcoil designs sound thin and irritating. By short circuiting the yoke we prevent this happening, which leads to a much smoother and more natural high frequency balance. The effect is quite noticeable, which is why we put a switch on the XX1, so that people could hear the effect." - Dr. Tominari (Dynavector Systems)
Speaking of the further development of the mighty Dynavectors such as XV1 and Te-Kaitora i would say that the long boron cantilever looks unprotected and extremely fragile. I would avoid using such cartridges for practical reason, but it’s just me.
