I have my dot stream to a BT receiver on my stereo. The audio is actualy not fantastic; I tried steaming from the mac directly and it's better, but then again the Spotify is still quite a bit inferior to the good old 320kbps mp3 I had in itunes... On some songs it's actually quite poor.
Might be my BT receiver box tho, plain old cheapo! Anyone has a suggestion for a good BT->optical and/or analog box?
Spotify streams at 320kbps on the Dot. Not sure what if the BT connection lets that down though. Audio quality is fine for radio and stuff, although if they do release a second gen version with a digital out I'll be all over it.
