For sub bass response for test cd try soundtract to movie Titanic. I use it to see what bass response speakers put out. Very dynamic recording. Almost every song is loaded with deep bass.
Music to test systems
If you were going over to someone’s house to evaluate their system and you only knew it was a high end system, what 5 LPs (if you are into vinyl) and 5 CDs would you take and for what purposes (test bass, imaging, soundstage, etc.). I have thought about this a bit and have not yet narrowed down either to just 5. I will post my answer once this thread gets going.
