Ryan,
I have owned the original Rega Planet and now the Planet 2000. Both players are very smooth. Planet 2000 has more detail. Maggies can be a little harsh with the highs. The Planet helps in this area. I currently have Martin Logan Scenarios and the difference is pretty clear. I haven't owned any of the other units you mentioned, though each is well respected. A lot of good has been said about the AR Complete Amp; but the CD player is a bit of an unknown. It will probably come down to how much you want to spend and aesthetics.
