"And those, who like myself will state that from the given specifications it is not possible to conclude anything about the subjective sound quality of the Amplifier."

And yet, on the other hand, you will persist in making comments like this:-

"For example, I can make an amplifier that unconditionally stable, has 120dB NFB at DC and very low measured THD at 1KHz. By having done this however there is a good chance that I have worsened some other performance parameters and elevated some forms of distortion normally well below the noisefloor to prominence, plus these distortions may resist measurements using traditional steady state signals."

Comments like these have nothing to do with the current SOTA in amplifer design; they simply muddy the waters and spread lots of psuedo technical bs around. You seem to want to have everything your own way in this discussion, and keep on regurgitating stuff that may have been applicable 35 years ago, but has long since been consigned to history.

" . . . There is enough in ancient AES Papers and JAES articles from Otalla and on the subject of thermal distortion"

Easily fixed. Apply more feedback.

No, my remarks are not tainted by presupposition. I have no idea who he is. As far as I recall, I had never heard of him before reading that article.

Science fiction writer and editor, one of the early boosters of Scientology. I used to enjoy reading his stuff in Analog magazine, but you could never take him seriously- he was a shameless huckster and avid proponent of pseudoscience. Great qualities for a fiction writer.

There was a white blues man from Louisiana with the same name also.

I am quite fond of the SciFi stories of the times during which he was active, they have a certain innocence and enthusiasm that our modern times no longer encourage.

How many more SciFi writers and people from the esoteric circles once had their hands in Audio and went to print in the 50's and 60's?

They certainly where by far more entertaining than the chemists and computer geeks we seem to get these days... And they where more often right in some sense, than totally wrong.

I can completely relate to his wife's complaint about razzy sound. Oversampling with CD-Standard audio is particulary good doing this... :-)

JC's wife would have had a fieldday with CD...

Razzy sounds and that combined with Noel Keywoods CD = 300% Distortion Editorial and measurements would have been "big audio dynamite"...

Ciao T

My wife took a writing class from the guy that wrote the script.

John Campbell wrote the short story "Who goes there?" a metaphor for the
McCarthy era. It was made into the film "The Thing" twice, with Carpenter's
version being much the better and more true to the original.
