I'm about to build up a desktop system for my HD 600, I've been thinking of getting the Audio gd NFB12.1 as my dac and Little dot mk V as the desktop amplifier, since my main source is laptop. And I listen to Classical music and audiophile cds. What do you guys think ? Is it a good setup to shine the hd600 ? Feel free to give any thoughts or comments !! Cheers.
