MFs engineers are past masters at extracting the best performance from any given chipset, and the M6 is no exception to this rule. The analogue stage offers a full 4V balanced output from a moderate 47ohm source impedance with a full A-wtd S/N ratio of 114.5dB and >130dB stereo separation through bass and midrange. The XMOS silicon and asynchronous drivers ensure there's no difference here between USB or S/PDIF inputs. Distortion is as low as 0.0009% through the midrange to 0.001% at 20kHz at this peak output, falling to a minimum of 0.0001% midband at -20dBFs [see Graph 1, below].
