As you predicted- us with no experience or knowledge still need to spout our opinions. I think I agree, but you're not saying that just the curve of the arches have to be beautiful, are you? I don't think there's any way "pretty" alone can produce better sound. But, that said, I can see that a maker capable of making a beautiful instrument, imparts those abilities to all the parts of the instrument, and the result is a well-made and beautiful instrument that typically sounds good/better. I can also see these better-made instruments commanding generally higher prices, and therefore, having generally better players as owners. Better players = better sounding instruments. Ron.
