Bytes Per Second
Hey, hope your enjoying your baby, I have myself an 08 s. I always tell people, and it always turns out to be a drag, the best deal is to change it upon CD's at one setting. For the radio it is entirely different, and the same with many mixtapes; where multiple tracks are thrown on a CD without proper editing etc.
For those situations, Mixtapes or home made burnt music you need to change settings each and every song.. Sort of annoying, but I always do it for the most optimal sound... So if your really looking for it that is my suggestion.
Using the general display to get to the settings will become more than frustrating especially as you drive and what, so I suggest to everyone press the tuning once; it activates the sound options. For quick and easy access and do your adjustments as mentioned.
The adjustment has to do with bytes persecond, many high quality CD's are well above 192 per second. Well that has a lot to do with clarity of the sound, so if you want to bump the best that is my suggestion. When I burn CD's I set it so that it will play as many bytes per second as choose on every track. Generally in the burning options.
Generalized setting for me is low bass, almost all the way left -3 or 4, treble slightly higher than equalizer; basically +1 or 2. Sub 4+ or 5 in the maximum output. Offset to the rear by -1 or 2 max give you theater sound =) Everything else is up to you, I leave the center +3 4. Everything else doesn't make much of a difference except worse sounding music.
