The music player with a difference - The built-in display

The Questyle QP2R is a mobile music player in which many things have been done differently from the "usual industry colleagues".

For example, the QP2R uses a razor-sharp, high-quality IPS display from Sharp with a diagonal of 2.4" (6 centimetres). A "normal" display - without touch function. What seems to be a strange decision at first glance is quite clever on closer inspection.

For example, a touch display requires considerably more space than the smaller display used in the QP2R. This leaves more space for the essentials: The circuit board used, and thus the best sound.

In addition, the QP2R has a robust rotary wheel that allows you to navigate through the menus and playlists quickly and at any time, no matter what hand you are using, no matter what the situation. And there are no fingerprints on the display either.

Then there's the power consumption. A small display needs much less power than a large display. So you can enjoy your music player much longer than you would with comparable devices.
The operating system used

While most portable music players run a more or less customised Android, we opted (again, as with the QP1R) for a full-fledged Linux from redhat.

Android offers a great basis and already comes with many useful functions, but a "complete" Linux simply offers even more possibilities and higher customisability compared to a prefabricated Android. This results in higher stability and reliability as well as more performance in the player.
The converter structure

In most music players, a "one size fits all" approach is followed. In the D/A converter, a single clock is responsible for all frequency ranges from 44.1 to 384 kHz and USB.

Not so in the QP2R. Here, the 3-fold asynchronous clock structure patented by Questyle is used. One clock is only responsible for 44.1 kHz and multiples thereof, one clock for 48 kHz and multiples thereof, and one clock for the asynchronous USB transmission. This reduces jitter (clock jitter) to a level that can no longer be measured, and the sound is comprehensibly improved.
The amplification technology

Conventional amplifiers use voltage gain, which has been identified as a limiting factor in bandwidth and speed.

Questyle has long used current mode amplification, which results in a huge bandwidth, ultra-low distortion of just 0.0005%, and an output impedance of 0.1Ω.

The result is a spatial and absolutely natural sound, regardless of the headphones.

This technology is flanked by a consistent implementation of strict bias control. This ensures that the unit always runs in clean Class A mode, which is a prerequisite for maintaining absolutely clean and stable characteristic curves.

But that's not all. At the same time, the amplifier is fully balanced per channel. This means that a separate pair of current mode amplifiers is used for each channel. It doesn't get more consistent than that.
The conversion of DSD files

In the Questyle QP2R, DSD files are transferred to the D/A converter in bitstream mode. There is no processing or conversion of the DSD files on the way to the converter. The sensitive files remain untouched and are only processed at their actual destination.

This means that the full bandwidth and spectrum of the music is absolutely preserved.
Best possible sound - even from the computer

The excellent D/A converter built into the Questyle QP2R is also open to use from a computer or laptop.

So you can use its exceptional qualities to give the music on your laptop or PC the same high-quality processing as the music stored directly on the QP2R.

Simply connect the QP2R to your computer or laptop using the supplied USB TypeC cable, install the appropriate USB DAC driver (under Windows) and the fun can begin.

Questyle HB2 with docked QP2R and remote controlAnd for all those who don't want to control track selection, volume or other things directly on the PC, Questyle also has practical accessories ready: The Questyle HB2.

This is the dock that matches the QP2R and is made of noble aircraft aluminium. It is fully remote controllable and outputs the music from the docked QP2R via the analogue stereo RCA output or digitally via the coaxial output. In best quality and with great comfort.

 
What else there is to know

The Questyle QP2R processes all common music formats such as MP3, WMA, ALAC, AIFF, FLAC (up to 32/384 bit/kHz) and DSD256 (1 bit and 11.2 MHz).

In addition to the "classic" 3.5 mm headphone output, it also has a balanced 2.5 mm headphone output and an optical digital output.

Its internal memory of 64 GB can be expanded by a maximum of 200 GB via a microSD card.

The device is available in two chic colours. Either a cool, elegant space grey, or the high-quality, noble gold tone.

With its battery with a capacity of 3,700 mAh, the QP2R manages a runtime of a respectable 10 hours, despite the power-consuming Class A operation.
