Okay, I got it to work now. I'm not using it with the m903. It's USB from an rMBP.
Thoughts so far...
This thing is huge. I have no idea how I could travel with it. It's about 14.5 lbs (compared to the m903's 5lbs) and there is an 18lb weight limit for carry on bags on Swiss Airlines. I can't even put this and a MBP in my backpack without being too heavy, and a backpack is the only way I can think to protect them since it will be with me on the plane. If I can't figure out what to do with it, I'll have to give it up. I don't need to just get it to one place and stay there. I need to get it to one place, then another, then another, etc. - often to places where I don't have an address to ship to. Any ideas here??
The HD800 sounds great. The improvement didn't necessarily blow my mind, but if I had heard this first I wouldn't have had any complaints. The bass is strong and I'm not sure if the treble is smoother or if the bass just balances it out so that it sounds smoother, but it works.
The difference between the LCD-2 and 3 is still negligible to my ears aside from just the slightest difference in frequency response, with the LCD-2 seeming brighter up top. I don't notice anything about "quickness" or dynamics though.
The T5P sounds a bit like crap. Now it seems recessed and dull and flat compared to the others even with the m903 as I originally had it. That must be a testiment to an improvement from the Burson for the other headphones.
EDIT: Okay, "crap" was a bit of a strong word to use for the T5P. I still like them. Everything else just stepped up a level. I don't think the T5P are really benefiting all that much from a better amp.
