Just got the Bluetooth adapter. Works nicely! I do have a question though. After doing some research on the Qualcomm APT manufacturer I noticed different frequency responses for different adapters, and bit rates. I thought that the adapter just sent bits into the receiver and all that was handled in the D/A chips there. Obviously I am wrong. Love an explanation on how that actually works. FLAC vs MP3(various bit rates) kind of stuff??? Is the adapter degrading my high quality FLACs?
