[QUOTE="VWBobby, post: 7996291, member: 624844"] If you want to use an iPod in your car, use a USB adapter direct to the head unit. This is the only way to avoid what is already a loss (using an mp3 player). This was all discussed about a month ago: [URL="http:////forums/general-discussion/562271-mp3-ipod-vs-c-d.html"]http://www.caraudio.com/forums/general-discussion/562271-mp3-ipod-vs-c-d.html[/URL] No, CD's are not compressed 320Kbps. No, 320K is not CD quality. Yes, you can hear a huge difference between 192 and 320K. MAYBE you won't be able to tell driving down the road at 60mph with the road noise. However, when there is little road noise, yes I can hear a difference in my car. Definitely different in the home. The only way to compress music is to remove information or abbreviate sound information in the areas where the codec determines is inaudible. If you are listening to a 192K or 320K MP3, try turning it up and see if you can hear the digital garbage that comes through. It will sound like a weird robotic crackle sound, especially on higher pitched sounds in quiet passages. You will not hear it on loud songs usually, only the quiet parts. Also, the bass and treble has been cut below 25Hz and above 20Khz. Especially the closer you get to 20Khz. This is why Kenwood and other manufactures have "expanders" for MP3 playback, to help get back some of the sound information that was lost in encoding. Lots of manufactures have come up with circuits or software to help improve the quality of MP3 playback, but it is still just a band aid for the problem (sound loss). [/QUOTE]
