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.

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.

Operation: 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.

As a classical music lover, you must be very critical of the equipment used. The audio sources, CDs, DACs, amplifiers and the whole system must have superb performance. As a portable lossless audio source with all Questyle core technologies, QP2R can meet all your needs and surprise you more than you expect with its professional performance.

When QP2R is connected to HB2, they become a high-end system with powerful and extensible features. Any speaker system with standard jacks can be linked to HB2 via its analog and digital outputs, then you can share beautiful music with your friends.
