Hi. I purchased Augustwest's pair of 600 Ohm DT-880s awhile back (for reference, I measure 580 Ohm). Unfortunately, I haven't heard the newer DT-880s to compare. I can say that I find the vintage ones very detailed and clear, but lacking in low-end punch. The bass reproduction is impressively accurate, but not present enough to hold its own amongst the rest of the spectrum. I suspect a change in amp and a little bass boost will make these cans amazing (I have yet to get around to this).
