It's not so much the tool as it is the carpenter. I think that I could hand Dave just about any euphonium mentioned in this series of posts and he'd sound glorious. It often comes down to appearance, feel, nuance, and things that are so subjective that the player might have to wander around a bit (and spend a bit of $$) to eventually find their euphonium "home". I personally think that's part of the pleasure of my euphonium journey (though my wife might not agree after seeing yet ANOTHER euphonium arrive on her doorstep). I personally keep gravitating back to Bessons. The sound just feels right to me in my style of play and I love the way the horn looks and feels. Your mileage will definitely vary, and those who make money playing their horns will have a totally different perspective.
