It's got a really broad range, which is good...but it can be hard to distinguish at times. I like using something with alot of "real" instruments and/or warm vocals when tuning or demo-ing SQ. One of my favs is the instrumental from the Chip's Ahoy commercial a couple years ago. I don't know if anyone remembers it and have no idea what it's actually called...it's like pops swing kinda stuff though....Alot of trumpets, snare drums, and a wide variety of instruments that can sound amazing on a nice component set.
