Exactly my point. I posit that the only reason DWs generally sound better than, say, a Pearl Export is that the player on the DW GENERALLY has been playing longer and thus is more willing to make the larger investment. This more experienced player will generally have a better idea of the sound he wants and how to achieve that sound. His expensive kit will also generally be surrounded by high end accessories (how many D-Dubs do you see surrounded by B8Pro cymbals?), which serve to further enhance the sound.
I know a DW player who changes his batter heads once a month, and his resos almost as often. Of COURSE his set will sound better than the guy who's been beating on the same heads for 3 years, regardless of the make of the shells.
DW drums sound different, no question, but I'm not convinced that they're worth the extra ca$h... which is why I play GMS instead.
