On these fairly easy to drive speakers, both will work fine, but my money’s on the Pass for a better sound at "normal. And on harder to drive speakers the Pass all the way every day.
But if you really want to get loud with these speakers they are are only 80db efficiency which means you want watts and that’s where the 450w Mac will beat out the 60w @ 4ohm Pass, in being able to go louder, but not necessarily better sounding.
