I did a head to head comparison a couple of years back. I was thinking that the newer Bryston would be a good replacement for my ARC CD2 which is the previous model to the CD3. Even in that comparison, it was a very close call. I had an ARC Ref 1 and a VT100 MKIII for the rest of the system.
As it turned out there wasn't enough of a difference to me to justify the expense of a new Bryston.
I also compared the Bryston to a CD3 in a store in Minneapolis. It that room on that day with unfamiliar equipment, it was hands down that the CD3 was the better player to me.
To my ears, the Bryston has a little more cloudy presentation and the ARC seems to be a little more clear and subjectively more involving.
