Talk's cheap. Provide link to any analysis, study or paper by any credible person, institution or group that proves your claim. The ear/brain precision and accuracy of some guy standing under a bridge doesn't count. Remember, kiddies, you can't dismiss what doesn't exist.

Surely one can measure THD and volume level (as well as frequency response deviations) to well below the threshold of human perception.
Even trained listeners can't hear .000001 percent THD or differences of .1 db.
Are we actually as ignorant as he claims? Do I really need to search for the links?
The poster says "aspects of" and thus only two aspects need to be supplied to support his contention. I have supplied the two.
We already found out a long time ago that Amplifiers with really low THD actually sounded considerably worse than many amps with much higher THD, even orders of magnitude higher. In other words you CAN hear .00001 percent distortion, it's just that it sometimes sounds worse than .005 percent distortion. So, where does that leave measurements? Answer at 11.
Yes, but not all 2nd order harmonic distortion is created equal. I paid a LARGE wad of cash and have rolled many a rare NOS black-gate or pinch-waist tube to get that elusive refined 2nd order harmonic distortion.Run of the mill 2nd order harmonic distortion is rather pedestrian, encroaching on mid-fi territory, really.

Now dat is funny! :)
That's right and certain kinds of distortion are actually preferable to many listeners. Long ago THD measurements below a certain threshold were considered moot - but last time I looked it wasn't unusual to see equipment with THD measurements above that threshold of audibility. But it's been awhile and I'm not so sure that it's true these days.I'm not one of those who thinks the "better" the spec the better it's going to sound. If there was an answer to what sounds best all equipment would sound the same.
Far as I know, for many manufacturers, equipment design isn't about achieving the best specs it's about achieving the best sound. And there's nearly infinite opinion on what sounds best.
