What is your "evaluation cd"?


I know every time I change a cable or componet, I have a "particular" cd that I play to evaluate the change. It may not be the best sounding cd I own, but it has some merit that I want to hear reflected in EVERY cd I play. What are yours??

Herbie Hancock: "Future Shock" (dynamics, fluidity, drive, air)

Magma: "Udu Wudu" JVC 20bit (dynamics, transients, tone)

those are the first two I always go for.
Lisa Loeb "Firecracker" - binkie music but extrememly natural recording. Also, has several "tasteful" 360 degree sound effects, as well as a well-recorded door slamming.
Wagner/Solti Ring on latest Decca CD - great music, best recording of strings esp. basses, anvil striking great test of amplifier clipping even at low levels.
SACD - the SONY sampler
I've used Jakob Dylan's "Bringing Down the Horse" because until recently, every upgrade removed some hash but still sounded noisy and distorted unnaturally at some places. To be specific, there are times when a highly distorted electric guitar is playing LOUD, and in the background, at very low levels, are a chorus 'oohing', coupled with high frequency synth, coupled with sticks on the rim, coupled with a high hat. The problem is all those faint high frequency parts can and will mush together with a low resolution system. To discern these different parts, I use a Monarchy DIP balanced connection to a Nelson MSB DAC with 24/132 upsampling and Power Base, as well as Monster Power HTS 2000 and numerous Quietline filters.
