Hi Arny! Most impressed by the two references you have kindly provided, although they're going to take me some time to digest: Douglas Self is clearly summarising about half a lifetime's work, & the distortion figures his amplifier designs measure at are astonishing. I wonder how long we will have to wait for similarly impressive loudspeaker performance, & ultimately whether our ears are up to the task of discerning how clean they are. The second article is very wide-ranging & all the more impressive for having been written in a language other than the author's native tongue. It's very useful stuff & may well come in handy for all kinds of future purposes. Bedtime reading for a while!
