This thread has been quite extraordinary, thanks so much for putting in the time and effort to do all of this work and to respond to so many people. I'm a pianist and a lover of classical music as well. I've been content with the HD 800's so far. I plan on buying a pair of the SR-009's sometime this year. After hearing them last week paired with a very good electrostatic amp, the Cavalli Liquid Lightning, I was amazed with their transparency. I'm just curious to know of your thoughts about the SR-009 compared to the Orpheus. I haven't heard the Orpheus, but I have heard great speaker systems, and even better, live orchestras and performers performing great works of music. What are the similarities and differences of the SR-009 and Orpheus?
