I play music that is stuff I want to hear. My system still surprises me how good it sounds, but it is music that is the purpose of the system.
I have a number of piano roll recordings done by Saint-Seans, Ravel, Debussy, etc, and while I marvel at their playing, it's a real treat to hear it sound so good. My system excels on voices and acoustic piano. It is fully capable of presenting anything I want to hear, at whatever level I want, in a very large room. The sound is a pleasure, but it is always in service to the music.
Music first or sound first?
I just thought it might be interesting to take a poll of those that put sound first and those that claim they put music first in listening to their rigs.
