QP2R 64GB High-Res Digital Audio Player

£1,199 Now £999

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 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, 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.

A remarkable headphone amp/DAC and one of the most self-confident bits of kit its been my pleasure to experience. It could also be the most neutral piece of hifi technology I’ve ever listened to. It is, in fact, the Switzerland of audiophile technology.

GOOD: Neutral presentation, spacious soundstage, price, transparency, clarity.

BAD: nothing
