Product Infomation  
Sense and Sensibility.

You love first-hand musical experience? Then you’ll know that regrettably dynamic headphones most often disappoint on the headphone outputs of CD players or amplifiers.

Some of the oh so manifold headphone types actually need up to 500 times more power for the same loudness than others – their impedances can easily differ by a factor of 20!

Lehmannaudio already solved this problem back in 2004: the Linear turns the “makeshift output“ of your amplifier into a gate to another perception.

The solid ground for this experience in the Lehmann style is provided by selected components and a sophisticated circuit design. Three optional gain settings allow an impressive listening pleasure with the most diverse headphones on the most diverse sound sources.

The fact that highly demanding users like the WDR (West German broadcasting corporation), the audiophile labels Aeolus, TACET and STS Digital as well as distinguished manufacturers like e.g. Sennheiser, Ortofon and Van den Hul put their trust in the Linear speaks for itself. And for good reason the Linear serves as an incorruptible preamplifierat the renowned The Masters studio in the Netherlands.

By the way, the Linear can also inspire your active loudspeakers to an amazing vitality, if you so wish.
But probably you just want to enjoy your favourite music – up close and without flavour enhancer. In this case the Linear will conjure up a happy smile on your face. And if you wish to enjoy music à deux, it won’t leave you on your own: two parallel outputs on a discrete solid-state class-A output stage will simultaneously feed two headphones of identical impedance with souvereign power without curtailing the listening experience. As soon as a second headphone is recognised, the line out will be turned off.

Furthermore the Linear USB auto-recognises an incoming USB audio data stream and switches to the USB input. Which makes it a perfect partner for your computer or your iPad!*Listen for yourself how shockingly three-dimensional the Linear
outlines an aural stage: with physical, deep lows, a filigree resolution and a downright weightless elegance over the entire acoustic frequency spectrum. Turn the massive, cushioned volume knob and enjoy your pleasant crawlies when getting to know your musical treasures from scratch!
