"...while on paper the iPod (Classic 160) has the same functionality as the Questyle QP1R, it lacks the expandable storage, the ability to play higher-resolution PCM and DSD files, and the capacity to drive a wide variety of headphones. ... if your primary requirement is for excellent sound in a robust and well-designed portable player, the Questyle QP1R should be at the top of your audition list." — Steven Stone, The Absolute Sound, February 2016

"The QP1R has an attractive and intuitive interface that most listeners master in a matter of minutes ... the QP1R is more than quiet enough for use with high-sensitivity CIEMs, yet it also has enough dynamic 'oomph' to yield usable and satisfying volume levels with comparatively power-hungry planar magnetic headphones. ... The player's fit, finish and build quality are simply exquisite, which comes as no surprise given that the QP1R is built by Foxconn — the same firm that builds Apple's products and the Sony PS4. In turn, the Questyle's sound quality is remarkable, which leads me to think the firm is on to a very good thing with its signature current mode amplifiers. Finally, the QP1R may be the only legitimate top-tier DAP contender that is offered at a near mid-fi price, which means this terrific player must be considered an outright bargain for the quality on offer." — Chris Martens, HiFi+, Issue 129

Three years ago, we sparked upon a plan to design a high-resolution portable music player (Digital Audio Player or DAP). For our first DAP, we set ourselves an almost impossible goal. That was, 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 all. We looked forward to it, as not just portable Hi-Fi equipment, but, as the future of Hi-Fi itself.

An Impressive arc body with a twin steering wheel design, supporting DSD128&24/192kHz PCM files, pure class A, discrete transistors and components, headphone amplifier, incorporating Questyle Audio's patented "Current Mode Amplification" to ensure warm and powerful sound, which makes the QP1 & QP1R masterpieces of portable DAPs.

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 needs to do with the audio files wich are as high level as the studio recording at very low power consumption. After times of optimizations for system operation, player programming, and digital audio circuit were required, Questyle Audio  ultimately achieved a solution.

Sound Performance is Our 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.

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.

 Satisfy Your Needs for Travel

-  Battery : 3300Mah , battery life up to 10 hours
-  A maximum storage capacity of 288GB means hundreds of albums in your pocket, and two swappable micro SD cards take your whole music collection along with you.
- The mobile universal Micro USB jack for charging anytime, anywhere, and supports charging while listening as well.

Shock Quietly

The integrated alumnium structural design, from roughing and finishing surface machining to CNC composition, and to a complete QP1&QP1 body processing line, improved quality of technological testing standards, finally assembled, tested and delivered under the highest quality standards by Foxconn.

Product Specifications

QP1: standard version
QP1R: reference version

As a Reference piece, the QP1R uses higher quality components, as well as, a more critical approach to the audio circuit, producing lower distortion (QP1R THD+N=0.0006%, QP1 THD+N=0.0015%) and superior sound quality.

The QP1R also employs a different PCBA, a larger internal storage chip (32GB), and a different version of software.
