I love the sound of my bare brass vintage tenor! It is at my tech's place right now for some set up and personalization work, and I can't wait to get it back. I have only played one Mark VI (about 3 years ago?), and I have never played a Barone classic, but from what people say, they are more comparable to the Mark VI. The Vintage is more along the lines of the old Conns.
My Vintage has a very complex tone and is mouthpiece friendly. I would not hesitate to recommend a Barone to anyone. In addition to the Vintage tenor, I own a classic alto, and just sold a straight/ classic soprano (only because I have wrist problems that flare up with a straight sop.).
Good luck in your search. Not trying to sway you, but for the price of one "good" Mark VI, you could have a full stable of Barones...:mrgreen:
