A few thoughts along what you've already written:
• The two biggest areas where subjectivist reviewers and their advocates go wrong is in making the proclamation that measurements give no information on how the product sounds. I think you have shown that to be wrong over the years.
• While everything you can measure can be heard (given the criterion and the method used), everything you can hear still can't be measured. That being said, the measurements and the systems used to make them offer a lot of insight into the item being put under scrutiny.
• The human senses are not perfect and neither are our memories of our sensorial experiences. While the test equipment John uses is not perfect, as long as it operates correctly it has no problem with flared up sinuses, migraines, tinnitus or any other factor that can effect human hearing on a daily basis.
• The sound of your room is just as important as the sound from your speakers. It's also easier & cheaper to improve your room sound and it can be done in stages to great effect rather than wholesale.
• Test equipment is a lot like a car: the most important part is the nut behind the wheel
Keep up the good work, you crazy guy!
Careful design is the most important aspect of product.
The "nut behind the wheel" might be a worst case scenario.
Every product is carefully scrutinized & measured, built with tolerances +/-, evaluated in laboratory settings, durability tested, production qualified, priced, packaged, weighed and compared with all known competitors.
Some folks might be "nuts behind the keyboard" but our JA isn't one of them.

... listening to and, more importantly, enjoying music - rather than focusing on equipment - one could have done so much worse than to have chosen the Spendor S100.
There is a current version of Spendor Classic 100 :-) ..........

John,
I don't know what your motivations were in posting this here, but it doesn't matter: I'm not going to allow Aczel's libels to be reposted on Stereophile's own website.
If anyone doubts JA's seriousness or significance to audio, I'll refer them to the Audio Engineering Society, which honored him with their Heyser award, which is a big deal.
