If you like the AKG sound of the DF, the DT48-series might sound "wrong" for your ears.
I wouldn't say "wrong" but "weird" in my case. I mean most headphones are wrong if looking for speaker like response. I just found my 240DF much more enjoyable to me and my modded fostex T50rp. My modded fostex and modded stax lambda pros were closest things I got to speaker like response. The 240DF is close to them and probably best akg I ever heard but are mmissing tad bit in technicality in comparison. I love the 240DF FR presentation though and midrange response. That's why it's my favorite and never parting with it.
On the beyer.. most people told me that but no matter what I did with the dt48a it just was weird to me. Had good clarity, wasn't lacking in the highs but, could tell it rolled off quicker than my fostex, pros, and 240DF. Kinda had just a drop off like the SA5000. That didnt what bothered me though. It just had like a weird timbre response but who knows maybe it's just cause how use I was to my speakers and current headphones before I got the dt48a on loan to audition.
