REAL MUSIC VS. SHOW MUSIC PERFORMANCE AT AUDIO SHOWS. PRESENTATION V. PERFORMANCE? WHY?

One of the things that I have noticed is the kind of music being played to show system performance.  Full disclosure I’m with Infigo Audio. But as an audiophile I think it is important to hear your music in these systems.  Which means non hi rez stuff.  Stuff you would listen to in your system at home. I try to play everything at shows to show our performance.  Some systems to me are all presentation not as much performance. I play funk rock pop classical jazz folk R&B as well as test track to show what a system can do across a genres.  I think it is important to show that a system can perform on all materials. Some systems look good in presentation and sound great on hi rez and test tracks but are not musical involving and may not actually perform well across genres. Thoughts ?
