Yeah that Boron cantilever is part of the secret sauce, when I read this I immediately thought of the AT MMs that should but don't have that: VM740ML, 750SH and the 760SLC. I have a AT OC9XSL which has the same line contact as the VM560 but it has a nice Boron cantilever (so does the ML and SH OC9 variants) and it sounds pretty much all around perfect. I have a 740ML and it does sound really good all things considered but it typically sounds like there is too much information in the upper frequency range and it could use being loaded down to like 34k or something like that, I have the capacitance overall at just under 200pf and while it does sound good it just has a bit too much delivery in the upper range, it's a marginal flaw as it sounds very good. Somehow I ended up with 3 of those SAE 1000LTs and I must say they do sound good in my system, since trying one out a SAE LT has been on the deck ever since, the one I've been using like crazy has turned out to be a low rider, to the point that it looks like the 'shroud' or whatever it is that the cantilever sticks out of is actually dragging on the lp surface! I noticed this about 2 weeks ago but there is no degradation to the sound so I just keep on keepin' on with it.
