Well, like I said, I barely remember each of their respective sound sigs; but I did try the Bryston for a longer period with more tracks. The b22 was not balanced, whereas the bryston was. From what I remember, the Bryston was more transparent and imaged a bit better. I'm gonna have to compare again!
Thanks for the recommendations, I'll be doing a bit of research I guess. If I can get a worthwhile upgrade in sound over stock while maintaining tube budget under 500$, then I may just buy the WA22 and whatever other SS that synergizes well with the HD800
