I had no idea until last year that bluetooth uses lossy compression. I was so disinterested in bluetooth I'd not read up on it at all. Then a friend complained to me that her classical recordings sounded awful when she used bluetooth from her ipod touch to her Bose something or other. I was expected to have the answer, but didn't know a thing about it, so I started reading.
Turns out bluetooth audio is like a quite low bitrate mp3 stream, no matter how good quality the source is. I assume BT was invented by nerds for control signals. Well, that's about all it's good for anyway.
No wonder the quality DAP makers are dragging their feet over bluetooth. They need to get their heads together and come up with something fit for purpose.
the latest/next BT standard talks about doubling the speed, so this should allow for pretty good stuff. now as always, for a standard or specific streaming method to work, you need both the source and the receiver to be compatible with it. otherwise the signal reverts back to basic BT stuff.
