Quad - I listen to a full range of music from classical to jazz to rock. That's what I love about this system. All of it sounds good. I'm really loving the recently released and remastered Living Stereo SACD's. The Shirley Horne tribute to Miles is amazing. Renaud Garcia-Fons "Entremundo" is fun music and one of the best recordings I've heard to date. To name a few.
Shventus - no pets, no kids.
Dgad - It's been awhile since doing comparisons in that I owned the Khorus X prior to the Firebirds. I've since listened to numerous speakers at CES over the past few years. Nothing in the same price range or lower has impressed me over what I have. I've changed everything in my system but have never had the desire to change the speakers. They provide fast and solid bass, open mid and sparkling highs. The soundstage is massive but realistic and imaging is right on. I'm not surprised they are on your short list. Good luck!
Thanks for all the positive comments! Wendy
