@georgehifi,
Obviously there isn’t a randomized, blindfolded study published on my supposition. My point is that the “distortion” straw man set up in previous posts is not, in all cases, wedded to the effect on the listener’s ear in real life. So, I chose to make an example at the extremes. Thanks to today’s technology, you can buy a receiver at Best Buy tonight for $300 having gaudier distortion numbers than the Lamm ML2.2 SETs; a unit that the vast majority of professional reviewers regard as among the very best sounding amplifiers on the planet.
