Tape is not even roughly linear, while any modern A-D converter will be
linear to within the limits of most test equipment.

I get your point and understand your passion, but I think you're taking
this way too far. Whether or not a recording sounds like the original is
far more dependent on the microphones (and their placement) and the
playback speakers than whether the recording medium is analog or digital.

Yes, the weakest link has been the transducers for a while now.

Analog recorders are remarkably good. It has always been the intent of
their designers to make them as linear as possible. Now I'll concede
that it's difficult to get THD down below 1% and frequency response over
the audio bandwidth flatter than +/- 1 dB, but those parameters are
easily achievable on a well designed and maintained recorder.

As I said to Scott, maybe I need to listen to more modern analogue
stuff. I sort of gave up on it when it became so much cheaper to get the
performance I wanted using digital gear. That and losing the razor blades...

When I mentioned processing, though, I was including things like Dolby
which are included in most recorders. Tape without a compander is just
too noisy for my liking, and there are artefacts from the compander I
don't like.

While a digital recorder will have lower THD (and THD isn't the best
measurement of what's wrong when you hear something wrong) and flatter
frequency response, but when it comes to real world sources and
listeners, a good analog recorder will do just fine. Where digital has
it over analog tape is that there's no flutter and 30 dB or more less
hiss. Bad flutter will make a piano sound "nothing like the original"
but it won't affect a railroad train.

True.

Now what happens between recording and commercial release is a different
story. The only reason why analog recordings (newly) released in digital
format aren't severely buggered at the tail end of the production
process is because people like you-know-who insist that analog sounds
better. So the record companies make it so, and charge extra for it.

Which is where I may be reading Thekma wrongly, but he seems to be
strongly linking the post production process with the format, when
that's not necessarily the case.

When I record something, I record it to sound accurate, then I ask the
client how they'd like it to sound. Even classical music people now like
a fair amount of gain riding or compression, as they've grown used to a
more limited dynamic range on a recording than at a real live show.
