Oppo PM-3 is actually pretty close. I think the Nad Viso HP50 is closer to the HD650 than it is to the HD600. Even then, it doesn't seem to be on the same technical level. The Oppo, on the other hand, does get pretty close, though it falls short of the ultimate resolution that one can get from the HD600 with much better amplification. The PM-3 stops scaling at some point... but it can be plugged directly into a mobile phone, so if you're into that.
