— What Hi-Fi
With three gain settings it gives you an impressive listening pleasure, keeping an eye on your needs anytime – and this using a vast array of headphones on the most diverse sound sources. In this context we have, of course, taken into account the varying performance requirements and sensitivity levels of the headphone types currently available on the market.
If you would like to share your joy at this quality of music reproduction with family and friends, our multiple test winner will be happy to feed two headphones at the same time. Of course, the listening enjoyment will remain equally fabulous then. The two parallel outputs of the discrete class A solid-state output stage provide the basis of this double musical enjoyment.
A propos: if you wish so, the Linear will also stimulate your active speakers to a stunning vitality. In every situation a magnificent sound, always striving for perfection – such is our Linear.
