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

If only I could spell 'favourite' !

Well I would have many but mine would be:
  • Nils Lofgren Unplugged - Keith don’t go.
  • Noordpool Orchestra, A Jazz Symphony.
  • For deep bass: Hans Zimmer / James Newton Howard ’Why so serious’ from The Dark Knight OST.
Always loved the bass on Lucky Man.
