For once I gotta disagree with you.
I sat at Finals in 2000 and could clearly hear a bright, pinched sound from Cadets compared to the Cavies (in addition to not hearing Cadets finish any phrases in their closer on the cd recordings)...and this from a guy who normally hated the Cavies.
BD, on the other hand, was truly a step up on the Bb and should have won brass in 2000 (and Cadets should have won brass in 2001).
