I also used the HFN test disc.
Which track(s) of which disc? The one HFN advertise at present?

Slainte,

Jim

The disk is HFN 001, not the "producer's cut".

The track is side 1 track 3, -20dB pink noise L + R. Just realised it
wasn't a sweep, but since I recorded it silent (didn't listen) I
didn't notice that.

Ah! That'd explain quite a bit. The graph of pink noise is virtually
identical to yours.

I used side 2 track 7 (full range system frequency check) of the HFN
Analogue Test LP, The Producer's Cut.
