FYI: Nelson Pass Interview posted at Stereophile

mullardel34 · 5th January 2008, 03:12 AM

Stereophile magazine has posted a vintage Nelson Pass interview from November 1991 (the interview is 'vintage', not Nelson...). The URL is:

http://stereophile.com/interviews/1191pass/

It's simply amazing to see just how doggedly consistent Mr. Pass has been in his pursuit of simple and elegant circuit topologies; apparently, thermodynamics don't apply to the "mind of Nelson", for there are certainly no signs of entropy encroaching...

Also, at Burning Amp last year he was stressing the same points about gradual evolution of products to keep a company viable from a business standpoint. He's still in business...

I liked the interview a lot!
I think Nelson is pioneer of audio design.
I admire him for his wide knowledge.
I didn't know he started out with speaker design.

I would have asked him what he thinks now of the audio design.
Lots of progress on topology has already been made if he still enjoys as much as when he first designed his 800A when everything was new a discover...new devices less competitors.....and so on....

great interview though!

That interview was done in 1990, and was printed two months
before I walked out the door at Threshold, so there's a lot more
to the story.

Amongst other things, you modified your position as to how practical single-ended amplifiers were. In the interview, you sounded like it would never happen. Then came Pass Labs and the Aleph series.

Define "progress".

Most of the current "progress" flies in the face of the article's title; definitely not discussing technology for technology's sake. Imagine 5v/us.

Sorry I couldn't help myself.

Thanks for the heads-up on the interview (I like the step back in time), innaresting watching consistency evolve.

Mike.

Nelson's methods may change, but his philosophy seems consistent over time. Given that he describes himself as a topologist--nothing more, nothing less--that gives him a great deal of freedom; especially since his words and deeds match. Others make great claims, but if you have a chance to see their schematics, it's often a pretty ordinary circuit that's been gussied up with a marketing term or two to impress the unwary. There's a mismatch between the words and the deeds.
(The cynic in me says that's the real reason some companies don't release their schematics...they don't want people to realize how utterly, mind-numbingly ordinary their circuits are. Gawd forbid the masses realize that the emperor has no clothes.)
