The QP2R is the second generation of Questyle Digital Audio Players (DAPs) as a well-designed and fine-crafted high-end portable music player with excellent performance.

Enjoy your high-end and lossless music by taking a top-tier QP2R portable player with a pair of high-end 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. 

Performance

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.

Full-balanced Amplification Design

Four groups of Current Mode Amplifier circuits are located on both front and back of the PCB.

Craft

QP2R basically maintains the style of QP1R, the iF Industrial Design Award winner.

The curvilinear machining of Gorilla Glass for the front and rear panels of the player is extraordinarily demanding on CNC processing.

QP2R uses a new patented technology of plane bearing on the mechanical steering wheel and the volume knob. The accuracy of this mechanical and electronic operation has a special attraction.

The Type C port for charging and data transfer has a precise mold and its inner bushing made of stainless steel is lustrous and scratch-proof.

System

Large capacity, customized battery has more than 10 hours battery life.

Special chip used for accurate detection of battery level.

64GB internal memory and 200GB micro SD card for external expansion.

"The QP2R improves on the original QP1R in several key respects. First, it provides an all-discrete, fully balanced, pure Class A current mode amplifier and therefore offers both single-ended and balanced headphone outputs." ~Chris Martens, hifiplus Read Full Review

I'm sure it will be awesome as soon as I figure out how to download music to it.

Very good sound, some design improvements
I listen to jazz and classical and paired with say JHA 13R2, this provides very full sound, intimate (like a closer stage) and narrower soundstage to say Sony NW1 (more airy and more functional). The metal casing feels good in the hand and slim. Firmware update : only 1 since I bought. LCD a little small visibilitywise but fine. The main flaw, still, is the click scroll wheel - tacky, very rattly sound as if something is broken loose, and uneven platter that "wobbles" abit - and otherwise a misfit compared to the rest of the nice well built unit - scroll buttons preferred. The volume control in contrast is smooth and very satisfactory. Further, the unit has a disproportionate tendency to catch on the bottom right menu panel option, such that you often can accidently brush it in your hand, causing menu jumps. Not a deal breaker though. I bought the dock to interface to my amp; abit overpriced but does the job. However, the sound via dock (and handy remote) is definitely not as spacious and pleasing as my former HM901S sound+HM Dock interface...maybe something to do with the way my excellent electrostatic amp treats the input sound from this player (my headphone is the Stax 009). Overall a very good sounding unit which is better for portable sound.
