The KAB with the high-impedence line input option would do the job. The only other feature one might
like in a professional transfer setting is balanced line inputs and outputs, but I'd venture to say
you'd be just fine using Henry Matchboxes if this was needed. The only other thing is, the KAB
offers pre-set combinations of turnover and rolloff. I'd prefer an option for each, but you can see
where the cost runs through the roof when it gets too fancy.
I can't tell if the Mac Daddy of old grooved media preamps:
has a flat output before the EQ options. I don't know their exact design, so have no idea if this
would be hard to add as a feature.
The more I think about this from an archival perspective, the more I agree with Paul that a flat
transfer should be made one way or another. The reason is that it may be very beneficial for an
archive. We've discussed all the problems with commercial copyright holders' vaults. What if an
archive is given the best surviving example of a record with commercial value? If they've made a
high-quality analog transfer, they can lease the digital file to a reissuer, keeping the rare record
safe in their own vault but allowing the audio to be used in its best form. The reissuer may prefer
to EQ the record to a particular curve, or to their own mastering aesthetic and taste. They can do
this with a flat transfer, either in the digital realm or the analog realm. Also, what if a student
of a particular instrument wants to use audio examples in a research project or thesis? They could
access a digital file, with no harm done to the rare/fragile media, and EQ to accentuate the musical
points they are making. This is especially useful for older 78 recordings, because the fidelity is
low and it may be useful to band-pass only the frequencies of the instrument in question. The key to
providing this kind of flexibility is to be able to do both a flat and equalized transfer at the
same time in an efficient workflow, in my opinion. Another example would be a very rare disk that a
collector may allow to be transferred, but only one playback is permitted. Do both and you're not
hamstrung by any inadequacies or controversies surrounding digital EQ.
