Try being the guy with M50tis, Tom.

$450 is not an unreasonable price for that setup, and it will make you happy for a heck of a lot less money than a brand new setup. I doubt a tweeter upgrade would work, as I'm sure there's a crossover upgrade involved as well. Probably cost a couple hundred bucks or something, but that's a guess.
