I have not hooked up a transport to my DMC-1, but thought I would mention that Dusty recommended a great tagging program called Music Tag. I download quite a bit of music and Music Tag allows me to name the files by Artist, Album, Track title, and add artwork, then I load the files onto the drive that attaches to the DMC-1 which can then find, recognize and play the music.
I have been using the DMC-1 since it was first released about 5 years ago. I found that its internal DAC is as good or better than my Schitt Yggdrasil. Curious if anyone has replaced the DMC-1 with something they like better?
