Many AES long term members appear to have blinders on, I.e., "overly old school." AES is like a monument to objectivism. You could even say tombstone.1. Wire and cable directionality.
2. The effect of objects not related to the audio signal anywhere in the signal or acoustic waves in the room.
3. Audiophile fuses
4. Vibration isolation
5. Demagnetizing CDs
6. Cryogenic treatment of speaker assemblies, cables, CD players, etc.
7. The WA Quantum Chip
8. The Red X Pen
9. Silver Rainbow holographic Foil

This is excellent, an ancient FM radio interview recording of Dick Heyser.
Listen for at least a little bit and you will get an idea what he was like and his passion for audio and what makes things tick.
The bone I was picking with "audio conservatives" like him, as I said before, with AES old school types is how blinded they often are to anything more than one sigma from the middle line, how awkward they are in the face of alien concepts.

Hi
I only met him once and that was in company where i already felt too small to say much.
I can't say i understood much of what he said then either, I mean i understood most of the words but not enough to understand what he was talking about. That was the same for Dr Patronis at the table (turned out later he was a great guy and was a friend).
I can say being sort of a fan that Dick looked at things differently that those who only know "by the book". He was a Ham radio operator, those guys tend to tinker and get into how things work, he loved Hifi, wrote for Audio magazine, he worked at JPL and invented and made the gear that found a lot of the shuttle in the ocean. He invented the first measurement system that could measure a loudspeaker's anechoic response indoors and that was my involvement.
He saw measurements a little differently, in a cool way that was hard to grasp at first.
He said " we measure what we do because we can, not because they completely capture what we want to know" Think Total harmonic distortion, made sense in radio but not audio because there are so many variables in how much a harmonic stands out...or not at all.
He said Nature does not have units, we use time as a scale because we can divide it up neatly but it is not a universal scale. For instance any event at 20Hz takes 1000 times longer to happen than at 20KHz so measurements like Group delay must be considered in terms of what frequency it is (how long it takes).
Put it this way, he was the first person to figure out how to take an anechoic loudspeaker measurement including the acoustic phase indoors.
How does one exclude all the sound except the direct from the speaker?
If there was something he heard in the things you mentioned, i am sure he would pursue them if alive today. He was a brilliant scientist that rubbed some conventional academic types the wrong way related to making large leaps, but audio was his passion, he made his own tools when none existed and it's hard to stop someone like that...except in his case Cancer in 1987.
In a real way he was one of Audio's Tesla's, not recognized and argued against as he lacked the depth of academic credentials needed for high level ivory tower credibility.
Yeah great exclude him, "he lacked credentials" because he was recruited out of Cal-Tec to work for JPL on satellite technology.

My old boss at NASA would sometimes say, never get behind anyone 100 percent. I suspect you probably helped support my contention that AES old school audio types have blinders on when it comes to sound. We all live in reality tunnels to some degree. Richard Heyser missed out on some great innovations in audio, the Golden Age of tweaks, as it were. Would he have disapproved? Would they have changed the road he was on, who can say?
AES always had a strong academic bent, that generally implies a pretty strong sense of where the official box is.
So Dick's big mission, the ultimate frustration was finding measurements that capture things he heard.
Maybe he should have hooked up with someone who was able to correlate what was heard with what caused it, Peter Belt. And yours truly. The opposite of an academic or objectivist. There is an entire universe waiting to be discovered by the intrepid audio pilgrim. People have developed very thick reality tunnels over the years, it's almost impossible to break through. People assume certain truths, the more their beliefs are confronted the harder they hold onto them.Made the scene

Maybe, not sure that the aftermarket accessory area existed then -or- where those folks were at 36 years ago when Heyser passed away.
Peter Belt originally was in the speaker business, ortho something. . Ironic, huh? I don't know when he veered away from audio speakers to tweaks. Ah! It's been almost 45 years ago, according to PWB website. So 70s. But there's nothing stopping YOU, yes? It's never too late. I bet you're not interested in such things, and you dismissed such talk as hog swallop a long, long time ago.
