Great thread. I'm on the fence about choosing between the Pass XA.25 and the Coda S5.5, but I'm leaning towards the Coda.
@earthbound you're right, there are plenty of raving reviews about both amps. It's really difficult to get genuine feedback about audio gear on the Internet with all those paid ads and sponsored reviews. Still, I’ve read a lot of positive comments here and on WBF about the Coda, and many people moved from Pass Labs to Coda and considered it a step up.
Actually, I just saw the first somewhat negative comment from @hickamore: 'The one thing lacking is the sense of huge black sky overhead that you get from superpower amps.' That makes me a bit sad, because it sounds like I’ll lose something special.
