Dynamic headphones vary far more than people realise. For the same sound pressure level the power needed with different headphone models can vary upto 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 of the amplifier driving them in terms of voltage and current. The selectable gain (0dB, 10dB, 20dB) of the Black Cube Linear effectively optimises 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 if you have an easy to drive low impedance pair of headphones or a difficult pair of 600 Ohm studio cans. Carefully selected top notch components and a highly sophisticated circuit design guarantee top performance listening pleasure. Now you can hear that ultra transparent sound and the explosive dynamics formerly known only from electrostatic headphones. An overdimensioned power supply with a huge magnetically and statically shielded toroidal transformer is included internally allowing a power cable of your choice to be directly connected to the unit. 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 two Neutrik headphone jacks come with gold plated contacts. The faceplate and the massive milled aluminium knob for the smooth running ALPS high grade volume control are available in anodised black or silver.
