The Questyle QP1R High Resolution DAP is a reference quality music player with an impressive arc body and a twin steering wheel design for easy maneuverability. Supporting DSD128 & 24/192kHz PCM files, pure class A, discrete transistors and components, a headphone amplifier, and Questyle Audio's patented "Current Mode Amplification," the QP1R ensures a warm and powerful sound. The QP1R includes high-grade components such as resistors and capacitors over the original QP1, resulting in higher resolution and performance.
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.
