I have to back up the Captain here, as well.
I'm not saying you don't, but if you have 40 years experience in audio (!), then I would expect that you would have, by now, come to realize that it's not the gear, it's the user, you wouldn't fall for imaginary sales guy hokum like "low end character and high end response," and you certainly wouldn't imagine for a second that the phrase "right from a Sweetwater rep" meant anything at all, or that your extremely friendly and helpful Sweeaterwater rep (you are a member of their special family, after all) had ever directly compared the two interfaces in question.
And yeah, that might be rude, but I've lost my patience with the Internet. it's not you, it's me.
