Me too regarding Nelson Pass designs. One of the few SS designs that to my ears really get closer to making music sound real other than , to my ears, a tube solution (preferably of the OTL variety) ideally matched with the speaker. It always comes down to synergy when making choices and this is not so easy. There are many speakers with difficult load characteristics that are superb that will not electrically match with tube amplification. There is no simple answer to this complex paradigm. Melding components together in a manner that makes recorded music sound real is not easily achieved by Tube vs. SS discussion, too many factors involved in the equation that is evidenced by the same questions continually being asked, IMHO.
I really appreciate the contributions of Almarg and Atmasphere (Ralph) to my better understanding of these issues.
