Product Description
A variety of inputs and outputs
On the K11 are USB*, optical and coaxial inputs as well as 4.4mm, 6.35mm, RCA line, and coaxial outputs*. Having more inputs and outputs than other typical entry-level amps means the K11 is more than capable of meeting your needs of putting together a capable audio setup.
Large power output
Under a 32Ω load, the K11 is capable of pushing 1400mW under balance modes. This allows it to easily drive many HiFi earphones and headphones to fully unlock their potential.
3 gain levels, 3 volume curves
The K11 has 3 separate gain levels, each gain level having its own volume curve. This allows the K11 to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder to drive over-ear headphones.
Specially-designed audio circuit and power supply
Within the K11’s slim build lies a specially-designed audio circuit designed for great sound quality. This is backed by more than 16 low-noise LDOs for precise voltage stabilization and powered by an external 12V switching power supply. All of this leads to a purer and more robust supply of power, leading to stable high-quality audio and thus truly enjoyable music all of the time.
