Thank you, Kenny, for reposting this article by Nelson Pass. I read it a few years ago and didn't understand it then. I still don't understand it, but I misunderstand it less now than then. Like you, it helps explain why I like the sound I do from my F-3's feeding my Brilliance for opera and chamber music with some symphonies thrown in.
Regardless, Eric's speaker are sooo revealing. I'm still tweeking minor speaker positioning. I still wish someone would tell me if I would benefit by moving higher up the food chain either in First Watt or Pass amps? Even though Reno Hi-Fi is generous in their return policy and trade ups, it still is a heavy lift for a retiree on a fixed income. But, for the sake of undistorted 3rd order sound...no pain, no gain (pun intended). Others on this lively thread are welcome to chime in.....But please don't try to convert me to tubes. I tried a modified Dyna-kit st-70 years ago and ...don't get me going. A real pain in the tochos for mushy sound. Excuse this ramble. It's late in Utah.
