Having a clean desktop is always an easy task when both the Black Cube Linear USB preamp and the Black Cube Stamp audiophile power amp are mounted accurately side by side like in the picture on the left.

Passive high quality speakers can be placed on the table giving you a nearly unlimited choice of models instead of having to use those cheesy little plastic „multimedia speakers“ from the local PC discounter. Why not have fun and superior sound even at work? Enhance your desktop listening pleasure now!

The Black Cube mounting kit provides maximum functionality with discreet concealment in places where a homelike atmosphere shall be preserved.


Lehmannaudio Black Cube Buffer

The name Lehmannaudio has long become synonymous for producing cost effective state of the art audio electronics. The Black Cube Buffer is a high end cable driver that satisfies the highest demands and is the solution for practically all problems with long cables or different levels.

Many music lovers have an affinity to puristic concepts like the so called passive preamps. Although there are certain qualities, these setups are facing problems with long cables. The sound is often too soft and weak. Highs lack transparency and bass impact is also dissatisfying. This is mainly caused by a high source impedance of the passive attenuators.

The Black Cube Buffer is the ideal partner: Due to the low impedance output driver circuit realized as high current Class A design without global negative feedback the music flows unaltered, artefact free and with all its inherent energy to the next following input.
BCbuffer

Another application for the Black Cube Buffer is the field of biamping where low efficiency woofers are combined with much higher efficiency midrange drivers and tweeters like for example horn systems. In many cases the gain reserve for the woofer is insufficient. Here the Black Cube Buffer can be effectively used for level optimization.

Weak output stages of any line sources can greatly benefit from the Black Cube Buffer. Especially variable outputs of CD-players are very often dimensioned inferior. This is mostly the reason why a seemingly puristic combination of CD-player, power amp and speakers is sounding dissatisfactory in so many cases. With the Black Cube Buffer such setups can turn into highlights!
