Looking at these 2 amps (among others but these are main ones). I know the CA has a higher power rating but assuming that 80w is not required how do these 2 compare in audio quality? I realize a home audition is preferred way to evaluate but in this day of COVID, that is not possible as most stores (US) are either online only or open by appt only. Also in my city there are no CA dealers. Appreciate any comments from those who are familiar with both the Brio and the CAX81. I know the CA has more features (DAC and digital etc) but looking for the sound, not the bells and whistles. Thanks
