Since 2004 the Lehmann Audio Linear has thrilled all music lovers who expect their hi-fi amplifiers to perform at their best also with headphones. Can this success story still be surpassed? Yes, it can – and how!
The Lehmann Linear USB II comes up with a digital-analogue converter of the latest generation and a fully revised analogue 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 Lehmann 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 pre-amp it joins the carefully selected components and sophisticated circuitry of Lehmann’s crowd favourite, the Linear, with the digital world.
Enjoy your musical treasures from PC, Mac or even your mobile phone in audiophile quality. Lehmann’s 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.
SSC damping feet decouple the Lehmann Linear USB II from its base and bring about quietness. In every situation a fabulous sound, always striving for perfection – that’s Lehmann’s Linear USB II.
