Dave,
I can't comment on which of the three you mentioned is best, but I can tell you that I currently have the Bryston up for a NO RESERVE auction right now here on audiogon. I never even took the thing out of the box and hooked it up or else I could render an opinion. Anyway, I suspect it will go for far, far, less than 4K and it is unused. Check it out! The auction ends this coming Monday, November 18.
