They went all in with external power supply for the modulator and the large discrete opamps from Weiss, while using the new fancier chassis... Price skyrocketed.
The Arthur 4222/E1 here is a lot more minimalist still keeping the module's excellent measurements and an impeccable build. Sure there will be even cheaper options in the near future, but to me this is a nice sweet spot in value.
Those Weiss Op-amps seem to be new audiophile darlings. Very popular with even very rational folks around here.
