Maybe one of those occassions where the theory and practice don't match?


Theory and practice always match, if it appears otherwise then you've
misunderstood the theory or there's some other factors involved that you
weren't aware of. The use of shunt capacitors acroos the replay heads of
analogue tape machines to boost the HF response was standard practice,
often these capacitors were switched according to the speed selected with
larger capacitor values being used on the lower speeds.

The cartridge is rather dull, not bright, and I know about the recommended
capacitative load, but that's not what I'm after. In the mid '70s, somebody,
and I think it was either Shure themselves, or possibly SME, published a
cartridge equaliser circuit which consisted of one or two resistors and a
capacitor, may have been two caps, and which had the effect of lifting the
lower treble suck-out, and the extreme hf droop. It also had the effect of
dropping the total output by a couple of dB as I recall. It's that circuit
I'm looking for and sadly can't find.

You can see the frequency response I'm getting

My other cartridges, using the same test LP are fine. As an example, my EMT
cartridge does this:-
