I would concur with the some of the above comments.
The Halcro is an amazing amp. For some it may lack that rounded class A type sound, but be in no doubt of it being one of the finest amps.
The Pass Labs I know less well, but they always sounded good if not still more conventional. The Halcro is so pure that it makes all other contenders sound distorted/grainy.
You have to try both in your own set up. It is the only way to be sure. I did notice the Halcro sounding different after a couple of days of use, I couldnt put my finger on it but somehow it opened up in some way. So leave them in for a few days.
Good luck sure youll be happy with either
