The Cute Beyond is optimized for a wide range of load impedances and it's suitable for most headphones from the Etymotic ER4P (27 ohm) to the AKG K240DF (600 ohm). This high bandwidth, extreme low noise design (lower than -107db) yields greater than 105 dB of dynamic range and and that surpasses the capabilities of human hearing; which means there's no headphone that it can't handle! It's also got two gain settings that are selectable by a rear panel switch to give you quick and easy optimization for both high and low efficiency headphones.
For all you tweakers out there, the Cute also features user changeable opamps and a Shunt/Series type input volume control to suit different tastes. Other characteristics to the Cute include both short circuit and thermal protection.
