What 50wpc or higher amps have a totally different sound from Pass Labs, in a good way?

Some crazy supped up class d maybe. For different, but as GREAT as?
Maybe.. I have a few good ones. But Pass.. Just one of my all time favorites, First watt, Threshold, Even some of the Adcoms like the 5800 series, monsters. Man could I get them to sing with a couple of parts.

At the level you are talking, there really isn’t a yin/yang just preferences of nuance. Going to a tube amp would possibly be considered a yin/yang, (SS vs valve) but the 30.8 is a pure class A amp so even with that more of a preference thing over a yin/yang.

A Sumo Polaris would be an interesting comparison to a Pass! Designed by James Bongiorno. 120 wpc A/B. His amps emphasised beauty over a stark, clinical sound! I have an Andromeda, along with two older Sons.

@jasonbourne - cool suggestion. Will check it out. 

Ayre on one hand, and Luxman on the other are good counter points.

Listen for yourself.
