Best test might be 24bit CD not MP3, internet radio, Droid, ect.
Unfortunately well engineered music isn't as plentiful as in the past.
One selection I use on a regular basis is 101 eastbound by Fourplay
from the Fourplay CD.

The first time I played it for my brother in law he asked when I installed
the sub. I told him the system is stock. Keep in mind I don't have your system.
Two songs later the music being played sounded terrible in comparison.
Conclusion? Sometime it's the recording not the system.
