People's view on high-end audio has changed in the past few years. It seems a bit out-of-date just to sit in front of those heavy and complicated traditional audio systems in a fixed room. While what's going on outdoors is really amazing. Fashionistas are now enjoying the high-end and lossless music by taking along a top-tier portable player and a pair of decent headphones. QP2R, a well-designed and fine-crafted high-end portable player with excellent performance, is from Questyle.
QP2R, the second generation of Questyle DAP, inherits Questyle's quest
and style.
The QP2R keeps challenging the conventional concept by combining outstanding
audio performance with unchanged size, doubled driving power without increased power consumption, fine craft at a reasonable price.
Meanwhile, Questyle sticks to their mission of taking audio performance and listening experience as their core values and achieving perfection in design and operation. In shot, QP2R has preserved and inherited the typical and professional genes of Questyle which are becoming perfect over time.
For the operating system, QP2R still uses Linux which has the inherent advantages on performance and stability over Android .

The QP2R operates only in the state of pure Class A when driving different loads, especially heavy loads, achieving the perfect listening experience.
Just like a car of two-wheel drive upgrades four-wheel drive. Four groups of Current Mode Amplifier circuits are located on both front and back of the PCB for a full balanced design.
QP2R basically maintains the style of QP1R, the iF Industrial Design Award winner, and keeps the impressive design of tucked waist derived from a curvaceous woman's body. The curvilinear machining of Gorilla Glass for the front and the 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 costs much to make a special equipment and a precise mold, and its inner bushing made of stainless steel is lustrous and scratch-proof.
The more complicated the world is, the more concise we are.
Just as a sport car stresses accurate shifting gears and a sense of ritual, or a SLR camera values rapid view of pictures among a huge number of files, most professional devices are mechanical and electronic control rather than touch screen operation.
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. Questyle's engineers and Foxconn' s R&D team have tested over hundred structures and materials. It takes over 14 months to develop and they apply for 30 patents for technology.
With Questyle's patented technologies “True DSD” and “3x Clock Asynchronous Structure”, plus AKM flagship DAC chipset AK4490, QP2R can support up to True DSD 256 and PCM384/32Bit.
