Although... surprisingly enough Studer made some consoles using LM301s that
actually sounded very good. I boggled when I discovered those things were
full of 301s. Then I looked at the schematics and noticed that almost all
of them were working at unity gain, or maybe a gain of five or ten at most...

The studio board we built at onion audio used LM301AN's, the military
version, which could run at a higher supply voltage, for buffer amps.


That sounds like the critical issue then - it's an impedance
lower-er, not a gain-add-er-er.


We
ran them just under their max. v. spec. The board sounded great.


Clipping* parts are clipping.

*realizing of course that they not have actually been clipping, but
there was distortion based in abuse of the parts on the basis of
expected Vout....
