What is your goto reference recording

I always used to use "Ah Um" by Mingus to test systems. It's well recorded and has diversity of instruments, enough to test almost anything except pipe organ or full blown symphony orchestra. 

I'm not sure a system should be evaluated solely on those last two.

I use the Bill Evans album "Waltz for Debby" to determine whether the system or device being tested properly shows off the magic of this recording.  If the cymbals don't shimmer, or the brushes aren't palpable, and the soundstage isn't a glow, I know there's a problem somewhere in the chain.
