Burn-in period just started. Initially sound was muddy, gluey, too sweet, no details at all. After 100 hrs as you can hear - sound is sharp, digital++, too technical. Digital glare is present on vocal. Rare opportunity to find R2R DAC sounding like Delta-Sigma! :) 500 hours left - according to owners of this DAC, it is worth to wait!
