Lehmann Audio - Linear USB II - Headphone Amplifier w/ DAC
The Linear USB II comes up with a digital-analogue converter of the latest generation and a fully revised analog board using the high-grade Low-Z Copper technology. Physical, punchy lows and a filigree resolution over the entire frequency bandwidth: you will never again consider your headphones just as a makeshift solution.
Keeping an eye on your needs at any time, the Linear USB II delivers an impressive listening enjoyment due to its three gain settings – even with the most diverse headphones on very different sound sources. As a headphone amplifier and preamp it joins the carefully selected components and sophisticated circuitry of our crowd favourite, the Linear, with the digital world.
Enjoy your musical treasures from PC, Mac or even your mobile phone in audiophile quality. The Linear USB II automatically detects an incoming USB audio data stream and does without an input selector switch. For double listening pleasure our new champion is ready to feed two headphones simultaneously and as a streaming preamp, it also spurs on your active loudspeakers to play with amazing vigour.
3S damping feet decouple the Linear USB II from its base and bring about quietness. In every situation a fabulous sound, always striving for perfection – that’s our Linear USB II.
