Great replys, thanks!
I have had the chance to try both at home now and as some of you have mentioned, there is NO discernable difference. If pressed I would say the Adcom might be a tad brighter(not in a bad way depending on taste)
I will have a better chance over the weekend to really compare as I just received the Byston yesterday. But from the early comparison the Bryston will go back up for sale. The Adcom is a very enjoyable amp, especially for $300 I paid for it.
