Cute Beyond headphone Amp

The Cute beyond Headphone class A Amplifier is the latest and the last of the Cute family. It is optimized for a wide range of load impedances, suitable almost all the headphones from ER4P (27 ohm) to AKG K240DF (600 ohm). This high bandwidth, extreme low noise design (lower than -107db) yields greater than 105 dB of dynamic range and exceeds the capabilities of the human ear, ensuring to handle any difficult headphones.

Two gain settings, selectable by a convenient front panel switch, allow for quick and easy optimization for high or low efficiency headphones. With user changeable opamps and Shunt/Series type input volume control to suit different tastes.

Other features include Short Circuit, Thermal protection, and external AC100~240V switch power supply.
