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.
