What is the One Test Track That Tells You Almost Everything About A System?

Audiophile Reference 1 ( First Impression Music)

Track 13, Constellation Starburst, Haydn Sym No 94

To best evaluate small  changes in my system performance, I focus on low noise for a quiet black background.  I have found this track to be an excellent gauge to reveil low level detail. The track starts with very low level percussion with delicate overtones.  It doesn't take long for me to see when I have made an audible improvement that may result from reduced electronic or mechanical noise. This often translates to improved musical performance across the board: dynamics, bass, imagining, timbre...  Careful of the loud crescendo a couple minutes in.

The “one” track?

One of many I use/play is Michael Hedges’ “Aerial Boundaries,” from an original 1984 Windham Hill LP, WH-1032

Having seen him play this on several occasions and played the LP a few dozen times since ‘84 I have a good sense of how it SHOULD sound “in real life.”

The LP is a good cut. If the system can reproduce the little detail sounds he managed to squeeze out of the neck of that guitar including the depth of bass notes, harmonics and “soundstage” I’ll go on to play other things.

Other things? Jeff Beck’s “Cause We’ve Ended as Lovers” Epic, PE 3409

YMMV.

"High Life" on Jazz at the Pawnshop. Live recording with saxophone, drum, and vibraphone solos.  

"White Bird" by It’s a beautiful Day. Hard rock with violins.

"Keith Don’t Go" on Nils Lofgren Acoustic Live. Superb guitar playing in a lovely space.

"The Lemon Song" on Led Zeppelin II.

And thanks to everybody for their suggestions. More software to enjoy!

"Nothing Else Matters" by Lissie on Covered Up With Flowers - EP.  Incredible guitar sound and vocal by Lissie.     

I’ve always used “Such a Woman from Neil Young’s Harvest Moon album for its range: rich piano, deep bass, his voice, and at the end gentle cymbals. 
 

And “You Look Good to Me,” Oscar Peterson trio: Ray Brown’s bass slowly bowed then turns into a jazzy pluck; Ed Thigpen’s drums push and pull from slow to rockin’ and of course the piano amidst it all. 
 

Plenty of others but my two go-tos for range, speed and depth.
