Questyle QP1R Portable Digital Audio Player

899.00

Made for Quest

Three years ago Questyle planned to design a high-res portable DAP. For their first DAP, they set an almost impossible goal for themselves. That is to make true music lovers and professional audiophiles obtain much more excellent conclusive Hi-Fi listening experience based on a portable body. This requires the circuit, the device, system architecture, industrial design and processes must be reconsidered. They looked forward to it more than just a portable Hi-Fi equipment, but also the future of Hi-Fi.

Munich Hi-End Show 2015 , Questyle released QP1 and QP1R officially.

Memorable arc body and twin steering wheel design, support DSD128 & 192K mastering-audio files, Current mode amplification in headphone amp portion, pure Class A all-transistor headphone amplifier to bring the warmth forceful voice performance, so QP1 and QP1R become a masterpiece of  portable DAP .

Technology must to be merged into pure Hi-Fi

Arc body shows QP1, QP1R to be elegant, aluminum machine body is emerged into tough texture and pure HiFi property. Gorilla glass of front and back reduced weight while increasing durability and technological sense. The Continuous innovation of the whole surface design, part of the hollow guard enhances the sense of design, the curved glass machining made extraordinary claims, the assembly between the glass and the aluminum composite material superimposed surfaces of CNC machining and assembly with to a severe test.

Professional Support for Audio Files

QP1 and QP1R support APE、FLAC、AIFF、WAV and High-Res audio files such as DSD128 and DSD64. Playing back much more of the original sound performance of music  than other Mp3 players and smart phones . As a Hi-End portable DAP, it requires support the highest level studio format at very low power consumption. Under dozens of optimization for operation system, the algorithm player, digital audio circuits , Questyle found the ultimate solution.

The new DAPs allows a 3X Clock structure design of the CAS192D, a 3X clock USB asynchronous transmission structure ensures a more accurate operation. A three clock integrated circuit with FIFO asynchronous architecture and three voltage-stabilized power stages ensure accurate sound. With fladship DAC CS4398 chips, the DAP can capture more detail hidden in the depths of music.

Sound Performance is a Priority

In the times of fierce competition between High-Res DAP and Hi-End Smart Phones, Questyle used the highly regarded flagship headphone amp CMA800R as reference and emerge the current model technology into High-Res DAP QP1 and QP1R when others hesitate to drive the headphone via BB or ADI . Hi-End audio amplifiers are designed by all traditionally discrete components and combined with Questyle’s current mode PCT patents on portable devices , also cited such a design, immediately return an unparalleled listening experience, but only general portable audio player output impedance 1/20 0.19 ohm output impedance, with low impedance switching function, whether it is only 8 ohms ear headphones K3003 or 300 ohms wearing large dynamic headphones HD800, can easily manage.

 

By Dozen combined model, nearly 100 editions, Audio precision more than 500 data and 500 times subjective sound recording, the ultimate perfect QP1 / QP1 are finally born.

 Patented “Current Mode Amplification” in headphone amp, 

all discrete components Pure Class A circuitry.
