"I Don't Know of Anything at or Near the Price That Sounds This Good." – Michael Fremer, Stereophile
The Black Cube from Lehman Audio is a classic among phono preamps. Since its product launch in 1995, the Black Cube has enjoyed cult status with vinyl lovers. It caused a sensation in the audiophile press, thanks to its compact dimensions and marvelous sound. In 2006, a brand new and greatly improved version of the Black Cube was introduced, and it has enjoyed just as much acclaim as the original product.
What makes the Black Cube unique? Think back to what it was like when you listened to your favorite LP for the first time. Which features of that music cast a spell over you that remains to this day? The Black Cube brings back that magic, casting a spell over each encounter with beloved music classics. Owing to its excellent components and sophisticated circuit design, the Black Cube's sound is faithfully reproduced and with plenty of ardor.
"I don't know of anything at or near the price that sounds this good," notes Michael Fremer in Stereophile.
"What you get from the Black Cube is a snappy, punchy performance that's exciting and cohesive," reports a What Hi-fi? magazine review for January 2009. "Timing is spot on, and music has that foot-tapping quality that makes you want to keep listening."
A Wide Range of Tonal Shadings and Explosive Dynamics
A wide range of tonal shadings and explosive dynamics are typical features of the Black Cube. These qualities are due to the high-precision passive RIAA equalization circuit located between two linear gain stages and designed using low-loss precision MKP foil capacitors. The high-grade input stages of ensure low-noise performance and are the same design that's used in high-quality mixing desks and microphone preamps. The custom-designed power supply provides a large amount of headroom.
Quality Plus Versatility
Due to the four gain settings provided by the Black Cube, virtually all common pickup systems from high-output MM moving magnet cartridges to MC moving coil cartridges may be connected. The configuration options ensure an almost unlimited freedom of choices. An extra slot for a custom impedance offers a matching termination even for demanding MC systems.
All resistors used in the Black Cube are low-noise metal film types. For the gain and impedance selection, Lehman Audio only used switches with gold-plated contacts. Lehman also provided an extra hardwired plug-in location per channel for a direct connection without a switch.
The versatility of the Black Cube is readily apparent when setting up the device. Thanks to the compact dimensions that are typical of the Black Cube series, you can easily place it very close to the tonearm of your turntable. The shielded cable is fitted with an original Neutrik XLR connector on the power supply side. Furthermore, the enclosure of the audio section is made of a non-magnetic aluminum, and its top cover is mechanically dampened. The audio section contains additional modules for efficiently suppressing hum, HF, and random voltage noise. The use of a double-sided audio board also offers additional ground planes for a zero-interference operation.
