What music is best for an Audiophile Society Meeting?

We are auditioning the Piega P10 loudspeakers and a great system including Audio Tekne and Audiomeca at the NY Audiophile Society Meeting on Oct 26th. We have been asked to bring a selection of music with us. What, in the opinions of those who have been to such meetings, would be the best type of music to bring along? A wide selection, a particular outstanding song or CD, or maybe a certain style of music that suits the atmosphere ~ what do you think?
