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.

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.

Thanks for your reply.  Can you say what sonic differences you hear before and after doing this supplemental break-in?

 

I do one or both of two things, when installing a used MC that has not been exercised in months or years: (1) Set VTF at the upper range of recommended for at least a short break in period, especially if you detect mistracking at a VTF midway between max and min recommended VTF, and/or (2) run the Cardas test LP cuts designed to exercise cartridges. On the old LP at 33 rpm, that was cuts 2a, b, and c, on side A, I think. On the newer version which is run at 45 rpm, those cuts are also at the beginning of side A, but I cannot recall what bands.

PRaT is a function of the turntable, not the cartridge, IMO, and is mostly BS anyway.
