Sony's sound processing in the Walkman players doesn't rely on off the shelf DAC chips. They use Class D design where sound processing and amplifying are done with a single stage. So it's not a conventional solution, therefore there's not a standalone DAC chip.Does somebody know what is the DAC chip used ? Sony does not seem to communicate on this
Also any experience with Sony ier-z1r in balanced mode?
Regardless, DAC chips to me doesn't mean anything. Dethonray DTR1 uses an ancient chip for market standards, yet it blows several DAPs out of the water in terms of pure SQ.
