• QP2R

QP2R, the second generation of Questyle DAP, inherits Questyle’s quest and style. It keeps challenging the conventional concept by combining outstanding audio performance with unchanged size, doubled driving power with un-increased power consumption, fine craft with reasonable price, which is seemingly contradictory, but solved perfectly by Questyle.


Features :

- Supports :  ALAC,  APE, FLAC, AIFF, WAV, WMA ( up to 32bit/384Hz), DSD64, DSD128, DSD256

- Follow the same 3X Clock design of the Questyle Audio CAS192D.

The 3X clock USB asynchronous transmission guarantees a more stable and precise operation.

To obtain first class sound performance, three correspondence level clocks (custom made in Japan), individually control multiples of 44.1kHz, multiples of 48kHz and USB signal transmission, dedicated for USB asynchronous transmission, reducing Jitter to undetectable levels. A three-clock integrated circuit with FIFO asynchronous architecture and three voltage-stabilized power stages ensure accurate sound.

- Current Mode Amplification

Such a design with output impedance of less than 0.19 ohms makes it easy to drive whether 8 ohm in ear monitors or 300 ohm in dynamic headphones.

- Pure Class-A BIAS Control System

Ensure QP2R operates only in the state of pure Class-A when driving different loads, especially heavy loads which achieves perfect listening experience.

- Fully-Balanced Amplification Design

Just like a car of two-wheel drive upgraded to four-wheel drive. For groups of Current Mode Amplifier Circuits are located on both front and back of the PCB

- Pursue Ultra High Fidelity Sound

  Nichicon F95 : Professional Audio tantalum capacitors

  Power inductors from German Wurth

  ALPS encoder

  Customized clock phase noise of -150dB from NDK

- New Scroll Wheel Design

QP2R uses a new patented technology of plane bearing on the mechanical steering wheel and the volume knob, which completely separates the electronic detecting and the sophisticated rotary bearings, thus the entire operation of the player becomes extremely accurate. The accuracy of this mechanical and electronic operation has a special attraction, and QP2R makes it more appealing. There are over 30 components in the structure of mechanical steering wheel and the volume knob

- Simple Interactive UI Design

  Another feature is the "Steering Wheel" control for menu, allowing a quick track selection of the QP2R

- Large storage capacity

  264GB means hundreds of albums in your pocket
