Sorry for not responding to this thread. I've been too busy listening... :-)
Let's just start by saying that the emo was around 1k, so it was really a financial burden and big decision for me to spend over 4k on a 2 channel amp. I don't regret it one bit, one of the best audio decisions I have ever made. First thing I noticed before I even played any music was the noise floor was non existent. I could hear noise from my uni-q when my ear was about 12 inches away from the driver when I had the emo hooked up. 4b3 is dead silent. The Bryston is much more dynamic (especially at low volumes), less harsh in the highs, fuller in the mid range, and has more punch in the low end. There is way more headroom on this amp as well. It is exactly what I was looking for. I upgraded the 2 channel first, because that is most important to me. I have a 5 channel emo that runs my center/surrounds/height, so now I'm looking to replace that with a 9B (eventually).
