I see this thread has slacked off since April. My 800 arrived a week ago and its is becoming a real game changer. I must suggest that you audition this unit in your home. Make sure it has at least 100 hours on it (makes a huge difference). IT is quite amazing, the sound stage is immense, layers of sound and the funtionality we have all been yearning for for years, but afraid to ask. I cannot say enough about its sound. I have owned Audio Research, BAT, Audible,and many others so I have a reference level to judge from. GO and listen. Let me know what you think. I am very impressed.
