Walnut V2 arrived this morning and installed the 16gb card I had prepared for it. Just 2 files, approx 600mb of AC/DC and 400mb of Dire Straits. No tags etc. as suggested on here. Plugged in my month old Hifiman HE-350's and fired up the music(yes I turned it on before plugging in the headphones....). Sweet holy f+&k, delighted I went through the hassle of making single files with no tags for entire collections would be an understatement. Non-flat response be damned, I'm a fan. Not sure how much of a factor it is but having to just listen to whatever song comes next without constantly looking it up and/or skipping to the next track made me relax and enjoy the music more than I have in a while.
