QUESTYLE RELEASES QP2R
Questyle has released the successor to its QP1R. The new QP2R portable hi-res player features Questyle’s newest current mode amplifiers and has four of them—two more than the QP1R. Questyle says the four current mode amplifier circuits are located on opposite sides of the PCB in order to significantly shorten the signal paths to improve the audio performance, such that the QP2R’s total harmonic distortion is specified at 0.0005 per cent. The new QP2R also reportedly uses a bias control system that ensures that all amplifiers remain in Pure Class A mode, irrespective of load impedance. The output impedance is said to be less than 0.1 . The QP2R uses AKM’s flagship 32-bit DAC, the AK4490—which can support up to DSD256 and PCM384—in combination with Questyle’s own ‘True DSD’ and ‘3× clock asynchronous structure’ technologies. Battery life for the Questyle QP2R is said to be in excess of ten hours. Internal storage is 64GB, plus there’s a microSD slot that can accommodate cards up to 200GB. Questyle specs the frequency response of the QP2R at 20Hz to 20kHz ±0.1dB and the signal-to-noise-ratio at 102dB. It measures 65×134×14.5mm (HWD) and is distributed in Australia by Audio Dynamics.
