CJ evidently bought up the assets of Counterpoint, when that operation went belly up. Counterpoint was a mostly tube base gear manufacturer that moved into solid state (FET) gear after digits became a thing. Why did CJ buy the name? Who knows? Perhaps they didn't want a possible competitor.
I owned Counterpoint tube gear. The preamps were probably as good as whatever David Hafler was selling, year earlier. But it looked like Mark Levinson stuff, and Dyna couldn't compete on that visual level.
For their part, ARC attempted an entry into solid state-- the 'analog module' shtick, but no one was interested in that. 40 or 50 years on, try getting your analog module gear serviced. Not like replacing a bad tube, I'll tell you that, for sure.
William Johnson began by offering Dyna mods. 60 years after, Dynakits are still supported via third parties. Dynaco is, to my mind, the ultimate in audio. It's never obsolete.
My guess is that Dave and Bill are, right now, having a cool one (or two), amazed that this stuff is a concern to anyone.
