Lehmann audio Black Cube Linear Headphone Amplifier
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 much more 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! Impedances can be different to a factor of more than 20!
This is the reason why different headphone models have very individual requirements to the headphone amplifier driving them in terms of voltage and current. Everybody who once has connected a high quality headphone to any given standard headphone output knows about this problem.
With the launch of the Black Cube Linear there is now a high end headphone amplifier to realize even the highest demands to reference quality headphone music reproduction.
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.
