Another favorite cartridge vanishes.. Dynavector 17D3. GONE! replaced..

5 grams heavier and $900 more. 

The way of the world in cartridge land. 

With respect to styli, "nude" does not necessarily mean that the stylus will not be glued to the cantilever (most in fact will be-laser mounting is another option); it simply means that the entire stylus is diamond. 

Bonded or tipped styli, on the other hand, will feature only a small diamond tip which in turn is fastened (bonded) to a metal shank which in turn is then fastened/glued to the cantilever. Cheaper, more moving mass, poorer peformance (usually) etc. 

I'd be really surprised if the 17DS is indeed "one piece"; if it's even possible to do I would think that the cost would be prohibitive.
