Sound quality difference with CDs on stock headunit

With Downloaded music being the majority of music these days I haven't played my CDs in a long time. Today I played my Santana Supernatural CD for the first time in a long time on my stock JBL head unit. What a big difference in sound quality and sound!! Have you ever played your favorite cd to hear the difference?

 

maybe EQ settings or downloaded music audio input/codecs.

 

Yeah, I did the same thing. The CD sounded really flat, then I remembered you have to adjust your sound controls for each option. It still didn't sound as good as my ipod, but it got better.
