The latest high-resolution Digital Audio Player from Questyle Audio is an upgrade from the highly acclaimed QP1R.

The stunning style of the QP1R remains, though the firmware has been completely rewritten and the electronics have been rebuilt from the ground up. The audio circuitry now takes up 70% of the PCB and includes a patented, fully discrete / full-balanced / current mode amplifier with ultra low 0.0005% distortion and less than 0.1Ohm output impedance. The amplifier is pure Class A in single-ended or balanced mode, and the DAC now supports PCM384 and true DSD256.

Other enhancements to the original design include higher storage capacity (64GB), upgraded navigation wheel, larger screen and an upgraded Linux OS.

Connect the QP2R to the Questyle HB2 HiFi Hub to extend the outputs of the DAP to connect with other HiFi separates and devices such as DACs and power amplifiers.
