Apple has blessed its latest iMacs with an improved 96kHz-supporting DAC (digital-to-analogue converter) and support for high-impedance headphones, according to a newly published Apple support document spotted by MacRumors.
The 3.5mm-jacked audio output stage on the refreshed 24-inch M3 iMac that has recently launched (and, it seems, on a handful of its recent Mac laptops too) has DC power load detection and adaptive voltage output features that can detect the impedance of connected wired headphones and better adapt its output for optimal sound quality.
