I see we have a member of the audio religion in our midst, how fun to see the scientologist poke their head out of their echo chamber. Arguing whether Class A is better than Class B is fucking retarded so let's not but the question of measurements is a fun one. Are you measuring something that actually matters or is it voltage swing in an electrostatic amp, meaningless stat that is measured in the one spot that makes it even more meaningless? If you go from 0.01 THD to 000.1 THD... how does that change the sound? Do we have hearing good enough to spot that or are we picking up something different? If something measures badly but sounds good, which is correct? If you claim something terrible sounds good... do you have enough experience to know it sounds bad? Just because you have ears, doesn't mean you know how to use them. Same goes with a scope or a test suite, just because you have it, doesn't mean you know what to look for. If you take a cult leader, hand him a device he doesn't understand because he's as thick as brick, he measures it incorrectly and claims "I don't understand why anybody think this is good"... was the device at fault or was the cult leader being retarded? If you smother everything in feedback, can you hear that? What if you remove all the feedback and make an unstable circuit, can you hear that? There are so many good questions out there...
