I'm in the market for a new DAP, but I have some weird requirements.  I currently have a Sony NW-ZX1.  Although it has Bluetooth, it is Android based.  I no longer want a DAP that is Android or iOS based.  I'd like Bluetooth so I can play audiobooks in my car, which does not have a line in or CD player (otherwise I would not normally use Bluetooth).  I would like to be able to connect it to my Sony PHA-2 amp, but since that will take anything that has a USB output, I doubt that will be the limiting factor.  I'll consider any price range, but I probably don't need the highest end DAP. 
 
The Fiio products look nice, but none appear to have Bluetooth.  Any suggestions?

Are these audiobooks in a protected format, or are they mp3 files you made from CDs? Only some players play protected audiobooks. You could use any player that will play the books, and add a bluetooth transmitter. There are inexpensive ones on Amazon. Choose one with a high rating.
