Hello Falconquest:
I have had the Vienna Acoustics- The Music since last December and must say I am most happy with them at this point, however I must say they have a long break in period for the bass side. The coaxial mid range speaker in the music center is pristine for female vocals and horns. Very smooth and dynamic. I power my speakers with Jeff Rowland equipment (925 monos, Chorus and PSU). All cables are Cardas and Shunyata. To me a great match of all cables and equipment.
Getting back to the basic question as to where they can be heard, I believe David Lewis Audio in Philadelphia has a pair on display. That is the dealer I purchased mine from and had a great experience dealing with them.
