@duke89061 First time with me personally ever noticing a change with burn in, which I was never a believer in. Now I am.
Ha! This has been a learning experience. Burn-in for many components is most definitely real phenomenon. I’m not surprised that the Accuphase DAC 60 is steady improving its sound quality (And will continue further). The substantial difference in voltage output was/is off putting as a new experience. I’m not surprised that the DAC is beginning to emerge as more clear, pure and resolved.
