FROM THE MANUFACTURER --------
Lyr 2 is one of the most flexible headphone amps available, offering both tube hybrid and all-solid-state options. What's more, you can even switch back and forth between tube and solid state as you like! Lyr 2 is a complete control center for your desktop system, with preamp outputs for powered desktop speakers, as well as a gain switch for use with virtually any headphone.
Amazing Flexibility for All Your Headphones Order Lyr 2 with tubes, and discover what a high-power tube hybrid amp can do. Or get LISST and go 100% solid-state. Or do both! No other amp (well, except Mjolnir 2) offers you this unparalleled flexibility. You also get gain switching and a 100% regulated heater and high-voltage supply that makes Lyr 2 fully ready for efficient headphones and most IEMs. And you'll have tons of power—our Dynamically Adaptive output stage transitions seamlessly from Class A to Class AB, for excellent overall efficiency.    From IEMS and Orthos to Active Monitors Lyr 2 offers two gain settings. The gain of 1 is good for most sensitive headphones, including efficient on-ear models and many IEMs, while the gain of 8 is ideal for inefficient orthodynamics and high-impedance headphones. In addition, the preamp outputs can easily be connected to powered speakers, for a complete desktop system.   Roll Your Own Sound Like Lyr, Lyr 2 lets you "roll" many different tube types to your own preference. Use 6BZ7, 6DJ8, 6922, ECC88, 2492, and many other tube types to get your perfect sound. Or choose LISST for a 100% solid-state, high-power amplifier.   Made in USA  By “made in USA,” we mean made in USA.
