Apropos of some stuff we were doing a while ago, here is the pink
noise track from th HFN-RR test disk played on my system, which is:

Systemdek IV
SME 3009ii arm
AT-OC9 microline cartridge

http://81.174.169.10/odds/dspkr/atoc9.gif

It shows an essentially flat response from about 12Hz, with a slight
lift at 10kHz, then returning to the proper level above that. The
recording is made at 96kHz sampling, and it is clear that the test
record cuts off sharply at 20kHz. The cartridge claims to go to 60kHz
(ahem!)

I've offset the levels of the left and right tracks slightly so they
are more visible.
