As for BT, anyone saying it's fine doesn't care about quality. A2DP is not lossless, it's compressed lossy audio (and has a bandwidth with a best case maximum of 721 kbits/s iirc) - so you take a lossy mp3/m4a/aac file, decode it, re-encode it using another lossy codec to send it over the wire and decode it again...and then you hope your BT device has a good DAC & Amp built in...
Some devices can send mp3 and AAC directly to the headphones to be decoded there. However that's really the issue with BT. Finding two devices that support all the right protocols over BT. The transfer rate on BT is high enough to do completely losses audio if someone would just implement it correctly.
