Guess we see things a bit differently. That's all I've seen is John chasing numbers of one sort or another. A quest for objective perfection.

No, it's to "win listening contests," which don't have much to do with listening.

I was a bit disappointed when Robert Greene, whose day job is as a highly respected maths guy, fell for the idea that a wide radiator (e.g. electrostats) has a wide radiation pattern. Quite the contrary Dr. Greene.

Did not you know that mathematics is humanitarian science, not technical one?

Are you sure he thinks that? --- Dr Greene -- Phd professor of mathematics in SoCal -- knows very well the dispersion/radiation pattern of electrostatic panels... The newer Quad electrostatics are wide and flat but they do have wide radiation due to unique design and not due to width of the speaker. I know Robert Greene and I also own a set of those Quads. -RNM

Richard, with all due respect, Robert screwed up and definitely was not talking about Quads.

Shame on you.

That's me, attempting to design the most 'elegant' electronics I can, keeping the measured distortion as low as the design approach allows.
AND I like to win 'listening contests' which can be 'formal' like that of a review from a name Hi Fi magazine, or 'informal' which can be: "Did you hear the audio system down the hall? It is really worth listening to."
I do not care to do ABX tests or their like. I already know their result, and I fault the test procedure as being flawed. Too many nulls, does not match the reality of the listening experience.

Thx... I also understand thatEurope does not allow the importation of GMO. Where-as, we eat 80% of our grown food as GMO. GMO is suspected as a cause of illnesses... and vitamin/mineral content is very low now. i use specific suppliments to boost the immune system and by all tests on me, it works super well. Do you take suppliments? -RNM

Shame on me. I'll talk to him.

I don't know that I would expect him to remember something he wrote many years ago.

The man is an eminent mathematician, certainly so --- I have even read some of his stuff. I wrote to him care of TAS when he made the blunder (which at the time I discussed with Floyd Toole, who generally regarded him as a cogent reviewer, particularly in the company of a lot of the rest of the TAS crowd) and I never got confirmation that he received the message. It was during a time that TAS was on the rocks, financially, so he may never have received the note.

But it is quite reasonable to assume that others with a knowledge of acoustics, and in contact with him more directly, did alert him to the gaffe. And with his quick intellect it may well have been but a brief reflection to correct his misapprehension. I was not at UCLA at that point, so couldn't merely go to his office and engage him.

To place the review, it was at the time RG, in the same piece in TAS, also described a room correction box ---perhaps one of the "best of" series. Name started with an "S" I believe --- it was one of the early ones, with DSPs the best of the day crunching numbers like hell wouldn't have it. Perhaps Demian (good at recalling these things in particular) may remember it.
