Three years ago, Questyle Audio sparked upon a plan to design a high-resolution portable music player (DAP). For their first DAP, they set an almost impossible goal: to make it possible, for true music lovers and professional audiophiles, to enjoy the same Hi-Fi listening experience achieved in state of the art home based systems, in a portable body.

This means, the circuit design, the device, the system architecture, as well as, the industrial design and processes, must all be reconsidered. They aimed for not just portable Hi-Fi equipment, but, as the future of Hi-Fi itself.

Style and Technology are Merged into Pure Hi-Fi

The Arc body of the Questyle QP1 & QP1R is so elegant. A machined aluminum body is merged with a Gorilla glass front and back, reducing weight while increasing durability and providing a better environment for EMI sensitive circuits.

The innovative continuous whole surface design, the hollow guard, the curved glass machining, the assembly of superimposed surfaces of glass and aluminum composite materials, the CNC machining and assembly to a severe test of specification, all of which are combine to make a beautiful and stylish enclosure.

Professional Level Support for Audio Files

The Questyle Audio QP1 & QP1R's support ALAC, APE, FLAC, AIFF, WAV, WMA Lossless up to 24bit/192kHz and high-Res audio files such as DSD128 and DSD64 playback reveal far much more of the original sound performance of music than that of Mp3 players or smart mobile phones .

As a Hi-End portable DAP, it converts the high level files as the studio recorded them but at very low power consumption. Optimizations for system operations, player programming, and digital audio circuit rebuliding & reenginneering was required, and Questyle Audio ultimately achieved a solution.

Sound Performance is the Priority

The Questyle Audio QP1 & QP1R follow the same 3X Clock design of the Questyle Audio CAS192D. The 3X clock USB asynchronous transmisstion guarantees a more stable and precise operation. The three-clock integrated circuit with FIFO asynchronous structure and three voltage-stabilized power stages ensure accurate sound. With Cirrus Logic flagship DAC (CS4398) chips, the DAPs are able to capture more details hidden within music.

"Current Mode Amplification" Headphone Driver Technology - A Legend of Questyle

In this era of fierce competition between High-Res DAPs and Hi-End smart phones, using Questyle Audio's highly regarded flagship headphone amp, the CMA800R as a reference and merging "Current Mode Amplificaton" technology is merged into a High-Res DAP, allowing QP1&QP1R to drive virtually any headphone.

Hi-End audio amplifiers are traditionally designed using all discrete components. At no spared effort and expense, this design protocol is applied to the Questyle Audio QP1 & QP1R and is combined with Questyle’s “Current Mode Amplification” PCT patents, and an all class A architecture. Such a design with output impedance of less than 0.19 ohms makes it easy to drive whether 8ohm in ear monitors or 300ohm in dynamic headphones.

For headphones of low impedance especially lower than 36ohms, low gain mode is recommended; for headphones of high impedance, high gain mode is recommended.

Incredible Audition Process

By times of testing completed model of nearly 100 versions (swapping out every component to find the perfect match), after analyzing more than 500 pieces of data and 500 sonic tests and audition recorded by Audio Precision, the perfect QP1 & QP1R are finally born.

Take heart in the details of the Design: A Simple Interactive UI Design

The helm style volume control and the machined alumnium hollowed-out protective crown inspired by a fine watch, against inadvertent volume change, and preventing accidental damage to headphone plugs while carried in a pocket or a case.

Another feature is the "Steering Wheel" control for menu, allowing a quick track selection of the QP1R & QP1.
