@ghdprentice +1 on adding Pass and Boulder. However the X or XA series are not integrated amps.
That being said, Pass Int250 or Boulder 866 should definitely be added to the list as well as Gryphon Diablo 300.
I own Wilson Sabrina (original) driven by Pass Labs XA30.8 amplifier. I heard the MA8950 in my system next to the Pass and prefer Pass. But that’s just a matter of taste. If you like McIntosh sound, go for it.
