I heard the Nagra CDP in a friend's system for several hours. I liked the sound -- clear, detailed and open, without being overly edgy and brittle. None of us preferred it over the Naim CD555 that it was being compared to, but, it is about half the price.
I also really like its look and compact size. However, it does have some operational quirks. If I recall correctly, if one operated the unit manually to start play on the machine, the remote control became inoperable. The remote was also quite weird and difficult to use. Ergonomically speaking, I would not agree that this player is well thought out.
