Here's what I think is going on, based on reading those who have listened to Pass and gave me more than pure fandom:
- Pass is an acquired taste
- Pass works best with certain old-school, high efficiency speakers, like Tannoy and Klipsch
If you have excellent hearing but didn't grow up with Pass or grow up with other amps that led you that way you are not going to like it.
The now old ICEPower ASP line is one I like to listen to more than Pass, after it has warmed up for a week.
I like ICEpower more than Pass. I like Luxman and Ayre more than ICEpower.
