I am thinking to upgrade my phone from HD590, but at this point I still have no plan for a dedicated headphone amp. I was pretty happy with the sound of HD590 directly out from either my Marantz CD5001 or NAD C325BEE's phone jacket. So the question is what could be the best phone (HD600/650, K701 or DT880) that be driven decently with the NAD amp? I listen classical mainly, and will prefer something comfortable to wear. Thanks a lot!
