To keep this on track, Halcro, did you use a torque wrench on your cartridge screws? The tension on cartridge screws can certainly affect sonics, for all the reasons you and others reiterate. If one were to draw conclusions regarding the efficacy of this or that fastener per se, then I think torque has to be a constant.
Solong, it's fascinating that you have already done research on titanium screws. Prior to now, had you drawn any conclusions? Thanks. I've just been using aluminum or plastic screws or anything non-magnetic.
Nandric, The best I can figure out is that my post(s) were deleted because I used the word "virgin", in the context of re-telling a well known anecdote about Groucho Marx and Doris Day. Since neither Groucho nor Doris will be reading this thread, I cannot believe it was because my post(s) might have offended them. Moreover, those two would have laughed and probably did laugh. By the way, Doris is a much under-estimated chanteuse. If you have the LP of her singing with Andre Previn, it's pretty good work.
