@jimmy2615 What benefits did you find running the amps vertically biamped? When you vertically biamped, did you use shorter cables between the amp and the speaker? I tried (for a short listening session) my amp (not Bryston) bridged last night and did not find it sounded better, in fact, it seemed the bass was less defined. As many others, I thought more watts would sound better. I am going to try again this weekend. I suspect the damping factor was the reason.
