Headphone operation at its best

The Lehmannaudio Linear Pro headphone amplifier in black is a top-class studio tool and has been developed for the best possible neutrality and transparency. Lehmannaudio did not need exotic components, unusual construction principles or a showcase-worthy design for the Linear Pro, because an expert selection of components, consistent engineering skills and a clear understanding of the requirements of everyday studio use were the guiding principles in the development of this extraordinary headphone amplifier.

The Linear Pro not only impresses with its linear transmission behavior and low distortion and noise values, but also maintains these values almost independently of the impedance of the connected headphones, whereby it manages completely without feedback that influences the sound. In addition, it produces a very clean stereo image with excellent channel separation and almost plastic separation of the individual signals. However, the main feature of the Linear Pro is certainly the extremely clean, distortion-free reproduction of transients, even with complex, highly dynamic material such as orchestral recordings or raw drum tracks.

For work at Studio and audiophile hi-fi enjoyment

Thanks to these practical advantages, the Linear Pro supports the sound engineer's work to a degree that should not be underestimated, not only because the quality of the audio material can be assessed with greater certainty, but also because the natural, transparent and slim reproduction allows fatigue-free working with headphones throughout the working day. These characteristics make the Linear Pro equally suitable for the discerning music listener at home, who can enjoy an unadulterated listening experience and the full grandeur of a professionally recorded and mixed audio production.

To enable the safe and stable operation of headphones with increased power requirements and to prevent dangerous volume levels caused by accidentally turning up the volume, the Linear Pro's power levels are set via Jumper on the underside. In this way, the Linear Pro works optimally with any headphones.
