QP1R is designed with Questyle Audio's patented “Current Mode Amplification” technology and a pure Class A architecture. With output impedance of 0.15Ω and high/middle/low gain settings, QP1R can perfectly drive anything from 8Ω in-ear monitors like K3003 to 300Ω dynamic headphones like HD800.
Inheriting Questyle Audio's 3x Clock Asynchronous Structure and patented “True DSD” technology, together with Cirrus Logic's flagship DAC chipset CS4398, QP1R is able to retrieve even the subtlest details hidden in the deep of your music.
Gorilla Glass is machined into a curvilinear shape
Gorilla Glass is used for the front and the rear panels, reducing QP1R’s weight while increasing its durability and technological aesthetics. The curvilinear glass machining is quite demanding on processing. The assembly of curvilinear glass superimposed on aluminum materials presents a severe test for the CNC machining.
