[net.audio] Turntable and cartridge query

kimr (12/02/82)

I would encourage you to get the moving coil cartridge.  My favorite 
manufacturer is Fidelity Research (I've got both an FR1MK3F and MC201).  I
have never heard a moving magnet cartridge which rivaled the transparency and
depth of almost any moving coil cartridge.  This is probably attributable
to the fact the moving coil cartridges typically have rise times on the
order of 10us, while moving magnet cartridges are in the 20-50us range.
The rise time of the human ear is somewhere between 9 and 14us.  As for
step-up devices, a used Marcoff PPA-1 will set you back about $60 (look
in the classified ads in the back of Audio magazine).  Other possibilities 
are:

  PS Audio head amp           - about $180
  Marcof PPA-2 head amp       - $225
  Audio Interface transformer - $225 as a kit or $300 assembled
  Verion MkI transformer      - $275 (used)

Regarding your turntable: you will be MUCH happier (if you get a good
cartridge) if you get a turntable whose arm height is conveniently
adjustable, preferably during play.  Vertical tracking angle errors of as
little as 1/8 degree are easily heard on a quality system.  Unfortunately,
every record has been cut with a different vertical tracking angle, hence
the need for adjustment during play.  My EPA-100 has a 6mm adjustment range
(1.5 degrees), which is ok for most records, but to cover all the records in
my collection, I would need a 20mm adjustment range (5 degrees). Watch out
for turntables with "adjustable arm height" that only have an adjustment 
range of 2 or 3mm.
