Bruno is quite impressed by his own genius---but in this case I think it is deserved. Michelangelo didn't think much of most of his rivals either, having none worthy until Bernini.Anyway, I appreciate BP's nonlinear dynamical systems/physics-oriented solution, understanding that orientation---very different than classical linear frequency-domain electrical engineering---was the key. I once worked on chaos-based communication systems (carrier wave is nonlinear chaos).
He also says something else pretty interesting about A/AB amplifiers:
BP: Well, if the amplifier is truly great that's absolutely right. Sonic signatures are what you get when you approach the same ideal from different angles. There are a few distortion mechanisms conspicuously missing in Class D, mostly those related to the input stage of a Class A(B) solid-state amplifier and nonlinear capacitances. Those are also missing in valve [tube] amplifiers so it's quite common for people to notice that a Class D amplifier is somehow reminiscent of valve amplification in terms of "sweetness" for want of a better word.
I've heard several reports of valve aficionados ditching their glassware and switching to Ncore. All I can conclude from that is that those people clearly weren't actively seeking the distortion of valves as many believe, but instead had a legitimate beef with certain sonic aspects common to most solid-state designs. That's one thing I have to explain again and again to my fellow doubters: when audiophiles report a particular listening experience, that experience is real. Trust that. Just don't trust the explanation they proffer.
