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.
Now, if you’re a headphone guy, you’re thinking “Holy Schiit! 6 watts! That’ll make the magic smoke come out of my headphones! Why the hell do you need that kind of power?” Well, we have one word for you: orthodynamics. And two more: Why not? If everyone wanted polite little low-power headphone amps, this would be one awfully boring world, wouldn’t it?
That said, 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 ECC88 tubes for the input stage, and the topology is DC coupled at the input and output to ensure the purest, most direct signal path.
