No, I really can't. I do it empirically, except to say what I already said, mistracking is a sign that the suspension may have stiffened up during storage. If increasing VTF to max recommended value cures the problem, then I assume the problem was due to stiffening of the suspension. Not very scientific.
Break-in period for an idle but used MC cartridge?
I recently purchased a Lyra Kleos cartridge that had been used for less than 50 hrs. last year and then put away. The seller, a collector of cartridges, suggested it would need another 20-30 hrs. of break-in. It's sounding good to me already, certainly not bright in an obvious way.
Has anyone experienced the need for a second break-in period for a MC cartridge that has sat idle for a while?
By the way, I agree with others who extol the resolution of this cartridge. It must have good PRAT too, because I often find myself tapping my foot when listening, which I haven't done so much when listening to other sources. Otherwise, it sounds similar to a Benz Ruby 2 I tried briefly, but it has more output.
