The Questyle Audio QP2R High-Resolution Digital Audio Player is an upgrade from the previous QP1R reference quality music player. Enjoy your high-end & lossless music by taking a top-tier QP2R portable player with a pair of decent headphones.
The QP2R inherits Questyle's quest and style with the second generation of Questyle DAP.
Questyle keeps challenging the conventional DAP concept as seen in the new QP2R Digital Audio Player. It combines outstanding audio performance with unchanged size, doubled driving power with no more power consumption, and fine craft within a reasonable price range.
Again, Questyle proves their mission of taking audio performance and listening experience as their core values and achieving perfection in design and operation.
The new QP2R carries Questyle's new design of current mode amplifier built with all discrete circuit and pure Class A working state. On the QP2R PCB, audio section covers about 70% of the whole device.
Due to the full-balanced output, the amplifier circuits are upgraded to four groups from the original two. Four groups of Current Mode Amplifier circuits are located on both front and back of the PCB, which significantly shortens the distance that signals bypass on the PCB. Thus the audio performance is improved, which gives QP2R 0.000% ultra-low distortion and less than 0.1Ω output impedance.
QP2R is the first portable DAP in the world to use pure Class A BIAS control system.
The Pure Class A BIAS Control system ensures that Current Mode Amplifiers operate only in the state of pure Class A when driving different loads (headphones or speakers), especially heavy loads, which achieves perfect listening experience and outstanding technical performance.
