You mentioned CD player. The reason CDs are still used...is because there is a 20% loss of data when streaming through Bluetooth. Yes it still sounds good or even great... but the FULL sound comes through in CD. Burning a CD from your computer gives you the best sound you can get from downloaded files. Have you ever cranked up the volume but not yet pushed play in Bluetooth? You hear a hum. Thats Bluetooth system adding distortion. Does NOT happen in CD.
