Radjammin: I don't know if you meant to ask if I'd ever tried the SAME horn in different finishes . . . OR have I tried the same MODEL of horn in different finishes?
To try the same horn, one would have to objectively blind-test the horn as is. Then tear the whole horn down, plate everything, re-pad, re-cork, re-felt, re-spring, re-assemble and test. Then, break it all down again, remove the plating (or lacquer - whatever), then reassemble the whole horn EXACTLY like it was when plated or lacquered, THEN conduct an objective blind test designed to duplicate the previous test. Then to validate the results, I'd guess that whole process would have to be replicated hundreds of times and some sort of statistical comparison drawn based on very subjective issues.
No, I have not done that - and to my knowledge, neither has anyone else. THAT is the main reason why us naysayers make the assertions that finish doesn't matter. Opinions are one thing, proof is another. True, I cannot prove my position either.
I have tested various models in different finishes (see my comments about the Antigua sopranos). Sometimes they sound similar and sometimes they sound different. But those differences are more likely to be the differences we all hear just because most saxophones are different regardless of their finishes. AND, when there were differences, they were not the typical silver-is-brighter results one would expect if one bought into the silver-finish argument (again, see my comments in the previous post).
