Czarivey,
this is unusual because Bluetooth by its very definition has lower bandwidth than USB. An audio file requires more bandwidth than Bluetooth can provide to provide CD-like quality. Unless your Subaru has aptX technology already built into it? aptX technology has been the secret weapon of Bluetooth for some time now - it's a codec that compresses the music file so that it can fit into the Bluetooth bandwidth while not sacrificing CD-like quality sonics.
Bluetooth is good for short distances such as 30-50ft (which is definitely the domain of the automobile).
Dont know of any Bluetooth preamps but the latest all-digital amps NAD 1030 & 1070 (which they demo'd at RMAF 2013) are BT capable.
Another British brand is Chord Electronics with their QBD DAC (I think I got the model correct?) that is also BT-capable. in later models BT was dropped because it was deemed quirky & not many people used it as the SQ was not very good (opposite of what you are reporting!).
You can send your data to these devices & in one case you can directly drive the speaker & in the other case drive a conventional preamp. There must be other brands that are BT-capable. The key, I think, is to have aptX technology so that you dont sacrifice SQ.
