Carbs: I believe good tone comes from the player, the set-up, and MAYBE the horn itself (in that order, in my opinion). If changing horns is out of the question (the Yamaha 23 is really bright to my ears - every one I've played), then a mouthpiece change would be next.
However, the pieces you listed all have good reputations. So, that leaves the reed . . . I have a Meyer 7M-Small Chamber and use shaved #2 reeds on it. True, I don't play it much, favoring instead several other pieces (like a Meyer 6S-Medium Chamber, Super Session J, Morgan-Bilger 6, etc.).
What I'm suggesting is that maybe you should reduce the strength of your reeds (except for the C**) and see if sifter reeds could give you more warmth in your sound. DAVE
