The CK300 headphone amplifier is a single-ended high-power headphone amplifier designed by our company with a direct heat pipe 300B as the power tube. The design is positioned for high-end headphones, from the design to the materials used to achieve the best sound quality.
The vacuum tube stabilized split power supply has a slow start function, which makes low noise possible; it has a multi-headphone impedance output and achieves a consistent output frequency response under multi-impedance, and a consistent sound quality performance. In order to achieve this function, after two years of development, this complex structure of the fully coupled transformer is the core of the 300B amp. Standard output four impedance selection and use relay switch, the impedance basically covers most of the headphone impedance. This machine's split-body bile stabilized power supply and electronic tube damping system, and the housing shielding structure allow the noise to be controlled until late at night and the interference of noise can be ignored. This machine has unbalanced and balanced dual input options, and the output ports have also been increased to three, which is convenient for different application environments. This machine follows the classic style of Rafael tube amplifiers, with a simple and elegant appearance. I believe that the production of this machine will be praised by more discerning earphone enthusiasts and it will be the best match for high-end earphones.
