@wolf_garcia Schiit, Klipsch, and Pass. Wait...that sounds like an instruction...sorry...Heresy IIIs are better than IVs, or so I say.
A triode obsessed "Inspire" preamp/amp buddy went from Hersey II, III, IV, to Omega for a while, and returned to the latest (revised) version of Hersey IV and likes it much better, notably so. Crossover, tweeter, port, design changes worked well in the new IV, fuller sounding and no fatigue now - he claims, fwiw.
