Lyr is a extremely high-output headphone amplifier with a new Dynamically Adaptive output stage that provides high voltage output into virtually any headphone-up to 6 watts into 32 ohms-while maintaining excellent overall efficiency. Lyr isn’t just about brute force. Sure, it has dynamics to spare, but it also delivers music with grace and finesse. Its hybrid design uses tubes for the input stage, and the topology is DC coupled at the input and output to ensure the purest, most direct signal path. It works by sensing the current flowing through the output stage, and dynamically reconfiguring from Class-A single-ended to push-pull Class AB. The result is both pure Class-A sound and the ability to drive virtually any headphone, including low-impedance and low-efficiency models (orthodynamics).
