owned both Mc501s and XA60.5s. Pass were more refined, transparent, better stage depth. Mac's had better dynamics & sense of command of the speakers. if i had bigger Pass amps, might have been an easy choice, but as it was, i kept the 501s (my listening bias is 1st and foremost dynamics & control).
tone is equally good b/w both. can listen to both all day, and i can say that about VERY few SS amps.
