That's what I keep on telling myself - hopefully my patience will eventually pay off. In the meantime I am on my second UNIverse cartridge and for some reason continue to have the right channel mistracking issue. Again the first one was a used cartridge which was advertised as having 75 hours on it so it should have theoretically been broken in and I traded it in towards a new one thinking that perhaps it was defective. The second one continues to have the same issue despite 75-100 hours or so. I've tried everything - two tonearms, three turntables, all kinds of VTA, VTF and antiskating adjustments, alignment and realignment with both the SME jig and a MintLP protractor, adding mass to the headshell, making sure turntable and tonearm are level, etc, etc...still the same issue. And as I've said the sound is otherwise so good that I'm just prepared to live with it and hope that it settles in for the time being. But all I know is that my other cartridge (a well-used Ortofon Kontrapunkt B which costs 1/3 as much) tracks the first three tracking tests on the HiFi new test LP and I never heard any mistracking on regular records - the UNIverse doesn't appear to pass either of these tests. Of course other than the occasional tracking issue on certain particularly challenging LPs the UNIverse sounds night and day better than the Ortofon.
Out of curiosity, how many hours are required for proper break-in?
