Umm, no I didn't... 
I had read that to properly run in the whole system (source, IC's, speakers, tubed pre, etc.) one had to run the CD at listening volume, so I just assumed the DAC would need the same.... so if for the DAC only. I just have to feed it a signal without the pre or amp involved??
I would listen to it right away, it sounds pretty darn good right out of the box, within a few hours you can hear it loosen up, listen to it all day and when you go to shut down your system at night, turn the amps off first, then preamp, and just keep the DAC on with a signal running thru it while you sleep.
I would run the DAC at full volume(5 oclock position), for those less then stellar recordings turn the volume to 4 oclock.
