“Which ESS chip, Mr McGowan?” hollered I. Despite the choice of decoder silicon being only one of several influencers of a DAC’s sound, consumers like to know.
McGowan spills the beans: “It is the ES9010K2M which is out of their portable series of reference DAC chips. We chose it from testing a bunch of different ones and found this to be the most musical. Because it was developed as a portable DAC we had some power supply challenges but those were solved by Bob Stadtherr in engineering. The choice of a passive filter after the DAC and before the output stage was critical.”
