Hi Vince, excellent point about dwindling NOS tubes. . . eventually these animals should be declared endangered species and given a modicum of protection against careless use by heartless audiophiles!
You have good chances of being correct about the future of class D amplification. Yet, it is a lot safer to study evolution with hindsight than using foresight. . . . at least for old and crotchety 'secular humanists' like yours truly. Perhaps 65 millions years from now some bookish techno-paleonthologist will examine the then famous Silicon-boundary layer in ancient petrified garbage dumps an discover an explosive growth in the fossil record of switching amplifiers. And perhaps a fossilized 'organism' with an especially unusual body plan sporting a transformerless combination of pre-silicon B-300 tubes and primitive switching amplification modules will be uncovered. . . a brand new techno-phylum will be assigned to it. . . and the specimen will be named Hallucigenia Atmaspherii by its discoverer--an incredibly distant descendent of Aloysius Qwantz Schmaltzenstein Gavronsky.
