Thanks! That's quite a lot of info.
A stupid question... What's the difference between "highs" and "treble", exactly? Do the DT48s have a more more warm or cold presentation? I tend to dislike anything too warm/dark, being a Grado fanatic (although I'm ready for something different).
Most importantly though, do the DT48s really knock the DT880s out of the park in terms of detail/clarity/realism for the extra 50-100 dollars? I heard somewhere else that the DT880 sounded "veiled" by comparison, but is it really a difference worth the extra buck?
