Good luck. 7.4.24 #75 30001 The name Lehmannaudio has become synonymous for producing cost effective state of the art audio electronics and is now introducing a new member to the worldwide known Black Cube product family. The Black Cube Linear is a headphone amplifier with preamp functions - or vice versa. The different types of headphones on the market have very different requirements to the headphone amplifier driving them. The selectable gain (0dB, 10dB, 20dB) of the Black Cube Linear effectively optimizes the output of the zero global feedback Class A output stage for practically all headphones available, no matter if you have an easy to drive low impedance pair of headphones or an ineffective pair of 600 Ohms studio cans. Carefully selected top notch components and a highly sophisticated circuit design guarantee listening pleasure on the highest level possible. Now you can hear that ultra transparent sound and the explosive dynamics formerly known only from electrostatic headphones. An over dimensioned power supply with a huge magnetically and statically shielded toroidal transfer is included internally allowing a power cable of your choice to be directly connected to the unit. The faceplate and the massive milled aluminum knob for the smooth running 27mm ALPS high grade volume control are available in anodized black or silver. Wooden face plates come as an option. 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 you can think of. All audio connectors including the two Neutrik phone jacks come with gold plated contacts. No external Y-adapter is needed! To get the very best out of your headphones you will have to try the Black Cube Linear.

Most recent version of this world-class phono stage. I am the second owner. Original box, cable and power supply include. This was bought originally in Germany, but is not fused and set for 120VAC 60Hz operation. Manual is original German. I can send the English version as pdf to the buyer, or you can find it on their website. Condition is very good ( slight rings on top cover, as shown).Info and reviews are online and on manufacturers website. It supports both MM and MC cartridges with variable gain available for both types, impedance and capacitance loading with dipswitches on rear. Standard values are 47K MM and 100 or 1000 for MC. Switch #6 selects a custom value which is presently 250 ohms. You can change this yourself by removing the bottom plate and plugging in the 1/4 watt resistor of the value you want into the solderless sockets on the main board. MC cartridges with outputs as low as .2mV are supported, I believe the max gain is 65 db with silent background.Ships to continental USA only. New ones are about $4.5K. Nothing wrong with this one.
