The Questyle Golden Reference System is One of Thē benchmarks for High-end Personal Audio, completely redefining what it means to be a flagship headphone system. What's more, it continue to  be a legend setting and guide future headphone system design, forever changing the face of Personal Audio.

 

Questyle Golden Reference System highlights complete separation of audio source, control, left and right channel amplification, even power supply, and each section has pushed the limits of their capabilities, which ensures enough details, dynamic range, clarity and power in any circumstance. The beautiful music and the dark background are so captivating that once you try it, you will not want to stop! The exciting feeling is beyond words.

Rogers Ceramic PCB

Besides the strict procedure in manufacturing, Questyle Audio Golden Reference System's one more unique point is it's the world's first audio device to use Rogers Ceramic PCBs. Rogers ceramic PCBs, a top level PCB mainly applied in military applications, allow the system to achieve an even more outstanding sound performance and specifications, some of the advantage are:
- Ultra-low distortion: 0.00022% (20Hz-20kHz) 
- Dielectric constant and dielectric loss are both the lowest available in audio devices 
- Ultra-stable dielectric constant in ultra-wide frequency (up to 10GHz) ensures ultra-low loss and stable signal transmission 
- Ultra-low thermal expansion , ensures stable operation up to 280 ° C temperature 
- Selected components, ceramic packages, provide superior performance in terms of system sound quality and technical specifications 

 

Current Mode Amplification

Current Mode Amplification is a state-of-the-art technology based on Current Mode. Current Mode Audio Amplifiers use transistors to amplify in fully discrete architectures, with a disaggregate structure designed in, to wit: voltage mode input and output, while the core amplification takes place in the current domain operating in a pure class A state. It is completely different from the traditional voltage mode amplifier, in the structure of the amplification circuit. Capacitance between the transistors, which affect the speed and bandwidth, operate at a very low impedance. It not only eliminates the TIMD, but also easily achieves amplification with a ultra-wide bandwidth (full-power bandwidth of 500kHz ), and ultra-low distortion (0.0002% , challenging the physical limit of audio testing). The Current Mode Amplification technology can be used for amplifiers of any power level (10mW-2000W) and of any size (thousands of square centimeters for some professorial amplifiers).
