Yes, I sure do miss Richard Heyser. He was the president-elect of the AES, but never assumed office due to a very rapid cancer. He was the most credible and visible of the "respected" scientists (PhD professor at CalTech) who was constantly trying to invent new ideas and methods to develop some kind of measurement that would correlate with what we actually hear.
He made a huge advance with TDS (Time Delay Spectroscopy), which allowed him to create the first waterfall plots. This was enormously helpful for loudspeaker designers (and soon after replicated by Doug Rife using his Maximum Length Sequence System Analyzer - MLSSA). Unfortunately, to date nobody has been able to do the same for electronics. John Curl and Matti Otala tried (many decades ago) with TIM - that helped make a lot of bad-sounding IC op-amps sound less bad - but it is far from a "final answer".
Which is fine by me. Just as we will likely never have the "perfect" car, I doubt we will ever have the "perfect" amplifier (or whatever). Cheers!
