I've heard the 8080s and own BPVXs and BPXs. I love my BP(V)Xs and was not that impressed with the 8080s in the showroom. Granted, they aren't comparable at all. The BPVXs have double of much bigger drivers and their retail price is double what the 8080s are. They are more comparable to BP2Xs with smaller drivers. My brother has my BPXs and a pair of BP2Xs and says that he likes the BP2Xs even. I bought those BP2Xs for $125.
I've only heard the 8080 surrounds in a showroom though, so maybe they're better setup in a real room.
