Agree totally with Tom -- in his first paragraph.
Beyond that, into the second one, he shifts from how well a cartridge (the
VRII) might play a record, into how it might wear a record out. Those are
two separate topics. While I myself have not experienced the wear-out,
owing to my discreet reluctance (not variable) to press ahead with repeated
playing, I can and do attest to its ability however to get great sound out
of 78s on the first playing. And on the second. Which is all one needs to
capture the signal.
While I've said this before, perhaps it's worth repeating: As a
practitioner of "high-end audio" record playing, I have applied many of
those unusual procedures to my beloved 78s, to success. Nowhere online have
I seen anything about these practices, so what should I do with this
abstruse knowledge? Seriously. I'm asking.
Please don't say, Make a cassette. Or, Make a CD. (I can't, anyway.) One
big improvement lies in the enhanced linearity of the bass, which requires
a full-range reproduction system to appreciate, which most folks don't
have. (Just sayin'.)
