It's not a one box CDP as the power supply and display are separated from the transport/dac (as opposed to most 2 box players which separate the transport and DAC), but the Resolution Opus 21 should be added to your list above. Its less expensive new than any of the players you've mentioned and in the same league as all of them. See www.resolutionaudio.com. Also, the size is only about 9 inches wide, so you could potentially fit both on one shelf.
Good luck in your search.
