I’m only reporting on amps with YG (with possible applicability to other sealed box speakers) - I don’t pretend to know about amp universality. I didn’t find much break in on the Pass.
Ya thats fine. I was just reporting my own findings so anyone reading there doesn't automatically conclude 'oh pass labs sucks'. I fucking love my pass amp. But I am not disagreeing that they may not sound good with a tube pre + YG hailey 2.2. I have no right to as I have not heard this combination. On the NS5000 they are magic.
