The Bass on Dave Brubeck's "Take Five" studio recording has been a pretty good indicator for me.
Good speakers have allowed me to distinguish the spatial difference between the note and slap/string noise. (The slap sounds like it is coming from a higher position than the note which sounds like it's coming from the body of the bass-like it would sound to you in person). This was through Dynaudio Special Ones, driven by Rotel 1080-BX. Source was cd played on a Harman Kardon DVD player
in an acoustically lousy small room with a tube tv and entertainment center between the speakers. I only mention it because your system/room and set-up are likely better.
