TG:
""I never said all measurements are useless. What I said is science cannot sufficiently explain the relationship of measurements to human perception of sound.
Bob, with his science, did indeed explain the relationship between measurement and sound. What is peculiar about his measurement, is that it was of a difference between two amps. He explained (actually proved), that by reducing some metric to a very low level, the amps would sound the same. He therefore correlated a metric to audibility.
The fact that the metric is not well understood is a moot point..the actual metric was a measure of difference in amplitude, and difference in time (phase, as it were). By reducing those entities, equality in audibility is achieved.
TG:
""Remember Bob Carver supports my statement when he admits he is not sure himself about the audible effects of some of the parameters he juggled to match the transfer-functions of his amp to that of tubed monoblocs.
A false statement of modesty. The "effects" of the juggling was to allow others to be inable to distinguish amps.
TG:
""Also IMHO Bob Carver futher supports my statement by NOT taking measurements of the "world-class" tubed monoblocs and interpreting what those measurements meant and then adjusting his amps accordingly!
Why do that which was un-neccesary? He knew what was needed to be done to achieve the goal. The challenge was not to explain the intricacies, just duplicate a sound.
Cheers, John
