I currently have the DAC 1 PRE and can say it is a very nice unit and simple to set up and use.
Walter, I would suspect the DAC's in the AMR 777 to be a step up, and should be for the like seven times price difference!
The DAC 1 is a solid and very musical DAC with clear and extended highs that are not harsh. when compared to my Esoteric DV-50s, it didn't have quite the soundstage or air, but was very listenable to, and did a great job even with high bit rate MP3's.
