dc, I was happy with the K601s however the AD900s had them covered in my opinion. I'm not saying they sounded the same, they have quite different sound sigs, however they do many things at the same level, Im hoping to get more of a difference from the DT880.
mrfloopy, I have had others talk about the Shure in-line and sound quality, however to my ears on my system, I don't believe the Shure attenuator has had a negative affect on the SQ. I'm interested in the RCA add on attenuators though, any links? As for selling the AD900s, looks like they will be going to one of my sons, provided I like the DT880s better that is.
