Headphoneus Supremus
Xenophon: I don't know if this is helpful or not, but in terms of whether there are audible differences among gear, my opinion is that if there ARE differences, it's easier to discern them with headphones than it is a home speaker system. I found this out with DACs recently. I've typically always been in the camp that DACs don't really make any difference, but I've now revised that opinion based on recent experience. The room is a confounding variable in terms of evaluating gear with a speaker rig, so when you take that out of the equation IMO it's easier to really hear the impact your gear is having on the sound. In a medium sized room, I had to put up over 22 acoustic panels before I felt that I had sufficiently minimized the room's impact on the sound of my audio rig...no such barrier exists with headphones. If I were you, I'd try to spend time auditioning different levels of gear (in terms of price point) to see what sort of results you get since you seem to value the opinion of the amp designer you cited. Just my $.02
