What is they best album out there for showing off the sound quality of your system.

Another one that comes to mind is Sting's The Soul Cages CD recorded in the short lived Q Sound.

Party Ball by Stan Ridgway on cd or Vinyl ia a great recording for showing off your system. 

As many here, I've a cadre of MFSL, Three Blind Mice, Chesky, VTL, Opus 3, RR, etc.  But going against all of these fine recordings is Gail Pettis "May I Come In?".  So well mastered, so intimate and a great talent with terrific support.

Also, Pepe Habichuela and Dave Holland "Hands".

@celtic66 Thank you so much for mentioning the Gail Pettis album, "May I come in?" It is terrific! It is a very intimate recording in that it is as if they are performing for you in your listening room. Gail has a great voice and knows how to tell a story with a song. This album is becoming hard to get, so don’t wait! Get it now. It just arrived today and I’m listening to it for the third time! I owe you one @celtic66
