Lewm, If you do not have a detachable head shell using Ti screws are asking for it. Titanium galls like crazy. You might get away with it if you use anti seize but I would stick with stainless or aluminum hardware (only using like nuts!) Some poor bloke is going to use ti screws on his SME V and permanently mount his cartridge. I wonder if Acoustic Sounds is going to pay for the mistake?
