Dear exaSound Team,
After listening to the e20 for a couple of days I would say it is an unmitigated success! I have been mostly listening to DSD files and they sound great.
I tried out the headphone output with my Senn HD800's and they sound fantastic with this DAC. I was surprised because the HD800 are a tough headphone for most headphone amps. My next surprise was when I hooked it straight to my amps. As I said I have tried several other CD players and DAC's straight into my amps and always preferred to go through my very nice tube preamp. Not so with the e20. I also really like the volume control and the balance control capability. I hear no issues with it and like the .5 db steps. I don't know how you pulled this off but I take my hat of to you!
