A good quality source makes a world of difference. I'm low tech old school and when I rip my old CDs, I use the highest quality (or lowest compression) process available. Just yesterday, the wife and I were enjoying a little ride around town while listening to the Eagles and a little AC/DC. She usually listens to music on her clock radio Mp3 player in her craft room and she was blown away with the rich sound and good clean bass....IMO it sounds great with Android Auto and HD Radio, but regular FM and some Sirius stations cam sound tinny.
