... most of us ASSUME manufacturing perfection regarding zenith, and most are unwilling to spend $1,100. for AnalogMagik, (even if aware of the possibility, and Wally’s error % findings) ...
Independent of zenith error resulting from manufacturing tolerances, the error can also result from poor phono cartridge alignment. That’s why I use a scored, mirrored gauge to align the cantilever itself, rather than rely on the phono cartridge body as a reference.
It’s long amazed me that so many audiophiles obsess over antiskate or VTF, but then completely ignore zenith.
