I thought my May DAC started to sound good at 100 hours, but the sound really does become exceptional after the reccomended 500 hours of break in. Also keep in mind that DSD and PCM are handled by separate parts of the DAC, so if you just play 500 hours of PCM stuff through it, the DSD side won't be broken in at all.
I use a Luxman JPA-10000i power cord with mine, which has got to be one of the cheapest power cord options out there ($125 on ebay).
