Maybe bias is the wrong word. Testing methods are different and Audioholics testing methods are more rigourous than most. I will have to dig it up but Gene wrote an article outlining testing methods, their idiosyncrasies, and what makes an accurate and more revealing testing method. Basic Amplifier Measurement I've read this many times and seen Gene use it in many of his reviews of amps/receivers. As fars as the links that I've posted, I can only show whats published on the web. I think their amps are way over priced but that being said, they far from junk. These amps deliver the power to even the most difficult loads.
