Charlie's summary does seem consistent with what I have read and what I experienced last night when I connected my new Blue Dot revision. I also experienced sort of a muffled, nasal sound for the first hours of play that seemed to have gone away. My hiss went from 10' at listening positon to 1'. Not bad. As the volume is turned up towards reference the hiss does grow maybe to about 3' or 4'. Still better than the consistent hiss at 10'.
I will post my specs and comments after further testing tonight.
