What is it?

People’s view on high-end audio has changed in the past few years. It seems a
bit out-of-date just to sit in front of those heavy and complicated
traditional audio systems in a fixed room. While what’s going on outdoors is
really amazing. Fashionistas are now enjoying the high-end and lossless music
by taking along a top-tier portable player and a pair of decent headphones.
QP2R, a well-designed and fine-crafted high-end portable player with excellent
performance, is from Questyle.

QP2R basically maintains the style of QP1R, the iF Industrial Design Award
winner: the impressive design of tucked waist on the surface with a twin
steering wheel, the helm style volume control inspired by a fine watch, and
the patented design of hollowed-out protective crown against inadvertent
volume change or accidental damage to headphone plugs. The perfect aluminum
finishing, the unbroken lines flowing with a smooth-faced structure, and the
curvilinear machined Gorilla Glass panels, all of which are telling that
Questyle has strict requirements on manufacturing.

It keeps challenging the conventional concept by combining outstanding audio
performance with unchanged size, doubled driving power with un-increased power
consumption, fine craft with reasonable price, which is seemingly
contradictory, but solved perfectly by Questyle. Meanwhile, Questyle sticks to
their mission of taking audio performance and listening experience as their
core values and achieving perfection in design and operation. In short, QP2R
has preserved and inherited the typical and professional genes of Questyle
which are becoming perfect over time.

How does it work?

As the "engine" of an audio system, Current Mode Amplifier, featuring a fully
discrete and topological structure, achieves ultra-high sound performance
close to recording scene that makes audience truly moved. Meanwhile, based on
the Current Mode Amplification technology, users can get much better listening
experience from QP2R than other devices when matching with their own
headphones or speakers which even though may not be the original matched ones.
Current Mode Amplifier can achieve excellent specs. For example, the THD+N can
easily reach ultra-low level to 0.0002%—0.0005% which is tens or hundred of
times lower than the ordinary professional devices, challenging the physical
limits of audio testing and bringing perfect listening experience. Just like a
car of two-wheel drive upgrades to four-wheel drive, four groups of Current
Mode Amplifier circuits located on both front and back of the PCB bring
stronger power.

With the high bias setting, just like a supercar is set to "RACE" mode, QP2R
immediately attains stronger power and quicker responses, fully improving the
mid and the low frequency sensitivity. There is a bias indicator on the side
of QP2R and it tells the standard bias indicated by orange light, and the high
bias by red light. It ensures that QP2R operates only in the state of pure
Class A when driving different loads, especially heavy loads, and provides
constant flow of strong power for the amplifier.

The Current Mode Amplification technology is first applied to Questyle’s
flagship headphone amp, the Golden Reference System which is used in Xinghai
Concert Hall (the biggest concert hall in China). Questyle Golden Reference
System has been used as listening device for recording master record of GSO (
Guangzhou Symphony Orchestra) for three years. As Questyle second generation
DAP, QP2R inherits the same Current Mode Amplification technology as Golden
Reference System. Although it’s in small size, it combines the best and the
newest generation design.

The 6063 Series Aircraft Aluminum is used for the chassis of QP2R and it has
been invested over 100 minutes to be carefully machined by Fanuc CNC machine
at Foxconn with the tolerence less than±0.02mm and the volume knob tolerence
less than±0.005mm. The bead-blasted and anodised aluminium chassis makes QP2R
attractive with a sense of exquisiteness and texture.

Just as a supercar stresses accurate shifting gears and a sense of ritual, or
a SLR camera values rapid view of pictures among a huge number of files, most
professional devices are mechanical and electronic control rather than touch
screen operation. The accuracy of this mechanical and electronic operation has
a special attraction, and QP2R makes it more appealing. You can truly feel it
only when you put your fingers on. QP2R uses a new patented technology of
plane bearing on the mechanical steering wheel and the volume knob, which
completely separates the electronic detecting and the sophisticated rotary
bearings, thus the entire operation of the player becomes extremely accurate.
In this part, there have been over 30 components used, over hundred structures
and materials tested by Questyle’s engineers and Foxconn’ s R&D team, over 14
months spent in developing, and over 30 patented technologies applied.
