Just read the thread. It's clear. He's a old-school, big iron amp fellow. In his opinion nothing else works. Overbuilt to look good on sine wave tests, regardless that it has little forbearance on actual performance considering the crest factor of music.
And then there is some weird twist about being "green". That seems a bit hypocritcal to me since those old-school amps are less efficient so you waste more power using them.
