I recently purchased a used Anthem CD-1 and had it upgraded/modded by Chris Johnson at Parts Connexion with: Audiocom Superclock II, Bybee purifier, new/better caps, Telefunken CCa tube and better RCA outputs. After about a month of listening, I can say that I am very satisfied with the sound of this player and the convenience of the 6-disc changer (much like the vertical cartridge systems in car audio).
Chris, who was the founder and designer of Sonic Frontiers/Anthem, said that the 6-disc changer mechanism in the CD-1 is very robust. Also, the power supply is very solid. Although its only been a month, I would have to agree, as my 4 to 5-year old unit appears to be working very well (phew!) and is quick when switching to the next disc (I don't use random much, as I prefer to listen to one disc at a time). It's a little more time-consuming to load and unload discs, since it has to be done one at a time, but it feels so solid compared to a caroussel.
This was not an inexpensive solution. However, for about $2,000 US, I don't think I could have done much better and still have the convenience of a changer.
