    Hi-end Analog Amplifier Technology

    Current Mode Amplification technology 

    Questyle Audio moves beyond the traditional voltage mode format design, employed in outdated modern amplifiers, reinventing the audio amplifier, by designing an innovative “Current Mode” amplification technology employed in all of our headphone amplifiers. The Questyle Audio CMA800R was the world’s first “Current Mode” headphone amplifier, exhibiting an ultra-low distortion level of less than 0.00038%. We have since, extended this technology to all of our headphone amplifier products including the QP1 and QP1R Portable Music Players (DAPs).

     

    Digital Audio Technology 

    True DSD 

    “True is the best.” Implementing proprietary driver software, Questyle Audio is able to send DSD source code directly from your computer over USB via bit-stream (as DSD was designed to be processed), bypassing the digital filters and digital volume control, to provide True DSD in the way it was meant to be heard, without converting it to PCM (thereby combining the deficits of both formats), or breaking up the bit-stream and compressing it into PCM packets (DoP – which makes extreme demands for extra processing at both the computer and DAC end as it must be compressed and decompressed in real time, as well as a 33% increase in bandwidth demand from your cabling and USB interfaces, not to mention the need to buffer a significant portion of the file in order to reassemble the bit-stream prior to sending it to the DAC, creating noticeable latency), or resorting to expensive and complicated proprietary computer interfaces. 

    IIR Digital Filter 

    Questyle Audio employs the most advanced IIR digital filter, which completely eliminates the pre-ring from the impulse wave providing the most natural sound possible.

    3 x Clock USB Asynchronous Transmission

    3 correspondence level clocks, individually controlling multiples of 44.1kHz, multiples of 48kHz and USB signal transmission, are dedicated for USB asynchronous transmission, reducing Jitter to undetectable levels. 

    Wireless Audio Technology 

    5GHz Hi-end Wireless Audio Technology

    Questyle Audio holds a PCT patent for its innovatively designed 5GHz Wireless Audio System, sending audio signal in the 5.2GHz/5.8GHz frequency bands, achieving a much more stable transmission, and providing true Hi-end Audio sound quality.

    “Questyle Audio Engineering is on the rise. With reviews completed or in progress from a number of audio review sites, the company’s visibility is growing rapidly. Everyone I’ve talked to, from end-users to journalists, seems very impressed thus far.”   

     

    “Combine Quest, Style and a passion for high-end audio and that what the company Questyle were born from. Now they are a new company in the respect that their products are only just on the market but as a company they have been working together since 2005 and only now do they feel ready to release their creation onto the world, I mean this amp I am reviewing from them went through 22 iterations so they were in no rush and wanted to make sure their products were going to reach the demands of the market.”  

    Our Enterprise Culture & Philosophy

    Respect and integrity, is the basic principle between Questyle Audio employer and employee.  Passion and dedication is our staff’s core characteristic, “Quest for Best” is our mantra. Continuous improvement of Technology and Acoustic Aesthetics is our Quest.

    Sound and Quality Control

    In our development stage, we use precise AP test equipment to measure and analyze sound, based on a technical index of dozens of specifications. On top of that, we conduct a host of special measurements to detect what that machine can’t. While specifications need to be top notch, sound performance is first and foremost. Before any new product is officially released, we invite select professional audiophiles to listen the sound, and verify what we have already determined.

    Many HiFi devices are “handmade”, as the market is not large, but we know that if we make our products in a modern factory, which is compatible with ISO system standards, although the unit cost will be much higher, we will achieve superior results. We believe, if sound is to come first, build quality is a basic requirement. For this reason, we selected a professional factory with professional equipment, standard work flow and strict procedure, to control  sound quality, and as well to ensure cosmetic aesthetic.

    Despite this, the final "age" testing is done in our laboratory; we leave this last section under our personal control. Before being shipped out, each product is tested with an index of over 30 items, and a key-factor test report is included in final packaging for consumer reference. Another copy of this test report is kept as our record.
