From what I remember, the D1100s got very uncomfortable and hot on my right ear after a while, maybe 30 - 60 minutes of listening. I had to have these cranked for a listen, yet at the same time everything just shot to my ears too much at once and all that the same time. The D1001s did not give me this problem at all and I found them more comfortable and, of course, lighter. However I think that it is probably more of a case that maybe Denon beefed these up more than I would have thought and I should have invested in a USB DAC for my computer rather than just use my line out of portable cd player, onboard pc audio, and JSLabs Cmoy amp. After returning these, I got the Beyerdynamics dt 990s and I thought they were kind of boring to listen to. Just nothing really grabbed my attention about the sound signature at all to lean on, sorry to all that disagree. So I ended up getting some Ultrasone HFI-15gs which were not only a lot less money, but a nice surprise in performance and comfort as well. Really I doubt that one can find a more comfortable pair. They leak a LOT though, and really need an amp bad. They have a nice silky smooth sound after break-in. Napilopez: Thanks for the comments and discussion. I am getting this Nuforce Icon uDac2 and am gonna grab some Samson's while I am at it. Ha. (SR850)
