Headphoneus Supremus
For a portable all-in-one, though not available now, I would go with the Sony D303 cd player. When hooked up to the external DC supply the internal amp can drive my HD650's to acceptable levels with a sound that is clean open and dynamic. With the Portapros it goes way beyound what I could listen to in volume. I was amazed the other day when I listen to it without going through my external dac and amp. The other Sony's have no where near this sound quality out of the internal amp, at least that I have experienced and I have most of them. After that the Xin micro IV would be the best bet for me.
