Do you have any idea how great your headphones really could sound? Hear a Black Cube Linear now and expect a surprise!
Dynamic headphones are quite different than most people realize. For the same sound pressure level the power needed with different headphone models can vary up to a factor of about 500! Impedance can be different by a factor of more than 20!
This is the reason why different headphone models have very individual requirements to the headphone amplifier in terms of voltage and current. Anyone who once has connected a high quality headphone to any given standard headphone output knows about this problem.
Since the launch of the Black Cube Linear there is available a high end headphone amplifier that helps realize the highest demands to reference quality headphone music reproduction.
The selectable gain (0dB, 10dB, 20dB) of the Black Cube Linear effectively optimizes the output level of the zero global feedback Class A output stage. Practically all high quality dynamic headphones available will show their best possible performance, no matter whether you have an easy-to-drive low impedance pair of headphones or an ineffective pair of 600?
studio cans.
Carefully selected top notch components and a highly sophisticated circuit design guarantee top performance listening pleasure. For stereo setups with just one source like a CD player or a turntable with a phono stage the Black Cube Linear is the simplest and most effective active preamp one can think of. All audio connectors including the two Neutrik phone jacks come with gold plated contacts. No external Y-adapter is needed!
The faceplate and the massive milled aluminium knob for the smooth running 27mm ALPS high grade volume control are available in anodized black or silver.
To get the best out of your headphones you will want to give the Black Cube Linear a try.
We have a comprehensive selection of Lehmann Audio devices available for demonstration in our HiFi studios in Berlin-Kreuzberg. We look forward to your visit!
