I was instantly surprised by the clarity, power and resolution this compact unit could deliver across a range of headphones.
Quite simply, the openness, detail and - above all - musicality of this amp brought our the best in every set of cans I tried.
It's ability to deliver the scale of a recording - and I don't just mean the big, bold stuff, but also the tightly-focused intimacy of a small ensemble - as well as the weight and range of instruments and voices.
The amplifier delivers all the weight and control of the weight... placing it all in a persuasive studio acoustic... but just that sense of 'rightness' you experience as soon as you hear the Linear USB II powering a pair of headphones.
...even hinting at music surrounding you... this Lehmannaudio amplifier resolves every element of the mix.
The intimacy of the sound and the clarity with which the Linear USB II delivers it, is spine-tingling.
The masterful control - and sheer energy - of the Linear USB II is totally captivating. Frankly, if you are serious about headphones, you have to hear it.
With massive power, fine detailing, deft control and total confidence, this is a world-class headphone amp, and makes some of its more complex rivals look overly fussy.
