I've actually been lucky enough to have a roommate (Aflac) who's been slowly working his way up, with me getting to hear his new acquisitions as they've come in. While the majority of my listening has been on SR60's and AD700's, I've had a lot of time with DT770's, AD2000's, K501's, HF2's and RS2's. I've also gotten the chance to listen to STAX Omega 2's, HiFiman HE-5's and HE-6's, and number of other sets in the $600+ range. From what I've heard, I'm willing to give up some of the impact of, say, the HF2's to have the kind of detail that the STAX can provide, and honestly I've made up my mind on the purchase of the STAX system! I appreciate the warning though; I guess this is what a new job and a signing bonus do to a soon-to-be college grad.
