Craig,
All very good points. I actually haven't gotten the Arcam yet. I just ordered it. I had purchased a Yamaha 3900, returned it, and just ordered the Arcam. I'm using my old Rotel RSX-1056 for now. I'm just wondering if I should just use the Arcam Amps, or maybe go with the XPA-3, which isn't as powerful and doesn't have the supposed clarity or quickness of the XPA-2... I can still send my XPA back, but obviously if there isn't an audible difference, since my Center channel is different than my mains, just use the Arcam's Amp for my Center channel and rears.
I can tell you are very analytical. Which isn't a bad thing, but like you said earlier, can be a curse...
I drive my girlfriend crazy when we are watching TV, movies and listening to music. There's something to be said to just sitting back and enjoying the content, rather than analyzing it...
