Rogers EHF-200 MkII vs Rogers KWM-88 Corona

Curious about member experiences with these two amps and any relevant differences. Signal-wise, I understand that the Ehf-200 has a stepped attenuator volume control and runs an EF86, 12AX7 front-end while the Corona runs 6SN7, 6SJ7 and potentiometer. The latter have less gain.

Whereas the Ehf-200 looks to be a very purist design, the Corona has a digital interface and a little less stated power (though I question the accuracy of Rogers specs). I have only heard a Corona driving Sonner speakers at CAF and thought it was sensational. That said, I assume I would prefer the EHF-200 for it’s EF86 and stepped attenuator combo.
