The Lehmannaudio Linear SE is a superb sounding and reasonably equipped headphone amplifier which can even double as a single source preamp if need be. Without neglecting even the smallest of details, this amp’s nonchalant style of play can instantly win you over. For those who have been critical or even disapproving of the headphone issue for sonic reasons, the Linear SE can provide a safe access to complete enjoyment. And those who already use headphones regularly will be wondering after several pieces of music if they can still trust their own ears. Because soundwise the new i-fidelity.net reference plays in the ultimate league!   Olaf Sturm
