I was going to take offence at your claim of Mark Levinson being a 'tweako
amp designer.' After all, his stuff may have been outrageously overdesigned,
but it was solid, technical stuff.

He didn't design anything. John Curl and Peter Burwen did the 70's stuff.
Tom Coangelo (sp?) did the stuff after that and who knows whose done the
design since. Chances are it wasn't Levinson.

This is typical of the 'high end.' Saul Marantz didn't design anything
either. Sid Smith and Dick Sequerra did the technical work for him.
