Got em yesterday, set em up last night, listened to a couple of master tracks for reference. That's all I've done so far. They sound pretty g-dam accurate and super smooth to me. Much better than the Roland pieces of crap I'd been wrestling with for the last five years. Why I didn't do this years ago, I don't know. I spent my money on great gear that made a real difference to my recordings, but this will save me HOURS - if not weeks, over the course of a year - of compensating for "wrong" mixes using my car as the final testing room. TIME, baby - it's worth the money, too.
