What would be your favorite 3 tracks that demonstrate how great your system sounds?

First-Magic Carpet Ride from any version of the album (Second) or any early version of Steppenwolf Gold.
This is most definitely not so in the recent Analogue Production version. Chad said that he used master tapes on each song on the album--- when available, but clearly, the masters were not available for that song as it sounds pinched and wooden and just awful compared to the Steppenwolf Gold pressing I use to impress visitors.

Second-RL version of Whole Lotta Love

Third-Low Spark of High Heeled Boys

oxygene [jarre CD]
buketoff arrangement 1812 overture
stereo version of eddy arnold/hugo winterhalter "cattle call"

Lots of stuff!!

 Pink Floyd,  mother. 
 Gary Moore,we want Moore!

Motörhead,bomber, overnight sensation. 
 Humble pie, rock on, eat it.
