I've had my Sonett with balanced outputs driving my HD800s for about one month now and it sounds fantastic. The Sonett is dead quiet and I am impressed. I just bought Alison Krauss' " Paper Airplane" and what a phenominal recording and the instruments just float, but her voice, as my wife says...

just got my 650's about a week ago and try to listen a little every night. how long does it take for them to break in?
