Clearly you have never had the joy of listening to a direct cut

I've had the joy of listening to the live sound in the control
room
where
it's being balanced/recorded. Only a good digital recording comes
close to
that. Analogue tape never did, and any form of disc recording a
very
poor
second.
Old Stan Curtis has an interesting take on analogue recorders;!
And a few other audio topics.

Now there was a chap who knew his onions.
If he does, he doesn't cover it fully in that article. More to
lining up
an analogue tape machine for replay than simply cleaning the heads
and
setting a level.
Stan Curtis AIR was for a while a reviewer/critic on Hi-Fi News
magazine whilst also designing amps under the Lecson and later
Cambridge Audio brands (or was it the other way around. IMSMC he
didn't pull the punches when he didn't like the design or sound of any
given amp. (Where's Jim LeSurf when you need him?)
If anyone is interested I found this web page with some details of
basic amp modules that he designed and were published in Electronics
Today International or ETI as it was always known in the early
80's-ish.

Interestingly I bought a faulty Toshiba SY-C15 preamp from a modular
hi-fi stack system from Neat audio (Neat stood for North East Audio
Traders) who had a secondhand hi-fi shop on the old GNR in Darlington
before they moved into designing and manufacturing some very nice
compact speakers at silly prices. The circuit was almost identical to
that of SC's design except that the input bootstrap pair were a single
substrate dual transistor, and the output pair were power transistors
similar to TIP29/TIP30. The fault was a blown TIP29 (equiv) in one
output stage.
Also interesting but again per SC's design the RIAA preamp used the
same circuit as the main preamp but with RIAA feedback. Line inputs
went straight to the main preamp which could also be bypassed by a
switch in effect leaving the volume control as the only item in the
signal path - it became a 'passive preamp' as the marketing bods would
later call such configuration.
Of its time it was a superb piece of kit; hum and hiss were inaudible,
it had very capable dynamics due to a well regulated PSU. The only
reason I had to get rid of it was lack of inputs!
