Aaron Neville "Everybody Plays the Fool" (if the system has issues with male vocals you'll know it here)
Stevie Wonder "I Believe (When I Fall In Love)" (For the sub-bass synth line) A real LF workout especially for vinyl
Jewel "Have a Little Faith In Me" (Or, just take the the whole 'Phenomenon' Soundtrack, almost every cut is reference-worthy)
Jackson Browne The Load Out/Stay (Listen for the feedback in David Lindley's vocal monitors on Stay @ 6:45 - the monitor mixer has them right on the edge, and doesn't panic, he just eases them off a few dB, and saved the whole cut - masterful work)
Everclear "AM Radio" (If the system can upack the layers in this mix, it can handle anything) And while you're at it listen to their anthemic version of "Brown-Eyed Girl"
Sonny Rollins "Saxophone Colossus" Any cut - pick one
The Mavericks "All You Ever Do Is Bring Me Down" Eee-hah!!
Charlie Haden & Pat Metheny "Beyond the Missouri Sky" 'Nuf said.
Paul Galbraith "Bach: Sonatas & Partitas" This couldn't be transcribed for a 6-string guitar - the finger positions were impossible - so he built a totally unique 8-string instrument with a second sound chamber, taught himself to play it, then transcribed and then played these 32 pieces. Just Amazing. And will test the midrange purity of any system.
