I have tried EQ before. While it does offer tremendous flexibility, it doesn't fix things on the "hardware side" of things. Granted, these are pretty small negatives we're talking about here, but if we can develop an inherent sonic upgrade then why not :)
EDIT: I must admit Mr. Fang did an incredible job on these cans, it's very hard to deliver a small improvement to the HE-6 even with Jerg and others spending tons of time and effort on improving the various planars.
