Lehmann Audio Black Cube Original Phono Stage

In Stock	An In Stock item is available to ship normally within 24 business hours.
Preorder	A Preorder is an item that has not yet been released. Typically the label will set a projected release date (that is subject to change). If a projected release date is known, we will include this in the description in red. Other Preorders are set to release 'TBA.' This means that release date is yet 'To Be Announced'. The Preorder can be released anywhere between weeks, months or years from its initial announcement.
Backordered	An Out Of Stock item is an item that we normally have available to ship but we are temporarily out of. We do not have a specific date when it will be coming.
Awaiting Repress	Awaiting repress titles are in the process of being repressed by the label. No ETA is available at this time.
Expected On	When an item is Out Of Stock and we have an estimated date when our stock should arrive, we list that date on our website in the part's description. It is not guaranteed.
Special Order	A Special Order item is an item that we do not stock but can order from the manufacturer. Typical order times are located within the product description.

Description

New & Improved! Dual Mono output stages, new input stages... A better design with better parts!

Great sound and versatility at a very reasonable price. Two PCB mounted DIP switches offer adjustable gain and loading options for almost all cartridges. Three gain levels, version 2 improves parts quality and adds chassis damping.

The Black Cube is a phono stage developed for the analog music lover. The small box can be placed near by the turntable, and a wide variety of pickup cartridges can be connected ranging from MC to high-output MM.

The passive RIAA-network of the Black Cube is placed between two linear amplifier stages - highly buffered special amplifiers by Analog Devices. This minimizes nonlinearities caused by phase errors that would occur in active filters. The use of low tolerance WIMA capacitors results in a very stable sonic impression with a fast attack response, delicate tonal balance and realistic soundstage information.

The external regulated power supply of the Black Cube can be placed up to 2m away from the audio section. The cable between power supply and audio section is shielded to keep RFI away from the near noiseless and highly stable supply voltages. This effect is enhanced by additional supply voltage filtering on the double sided audio PCB.

Analog guru Michael Fremer gave the Black Cube his highest praise in his Analog Corner column in the October '98 Stereophile: "...get your hands on the Lehmann Audio Black Cube. I don't know of anything at or near the price, or maybe even twice the price, that sounds this good." Stereophile rated Class B.
