Sonic Characteristics:
- Gold-plated connectors: warm, full-bodied midrange.
- Rhodium-plated connectors: fast, lean, and high-frequency focused. Many audiophiles, including Jaguar, combine gold and rhodium connectors to achieve the optimal balance for each component.
Advanced NCF Technology
These connectors feature Nano Crystal² Formula (NCF), a proprietary Furutech material with two active properties:
- Generates negative ions to reduce static.
- Converts thermal energy into far-infrared energy for improved stability.
NCF also incorporates nano-sized ceramic particles and carbon powder to provide superior piezoelectric damping, reducing vibrations and improving overall signal integrity.
Magnetic Floating Field Damping
Electrical current naturally creates magnetic and electrostatic fields around connectors and cables. Small metal parts in standard connectors can generate “floating” magnetic fields that interfere with the main field, causing noise and distortion.
Furutech’s Floating Field Damper addresses this by star-grounding all metal parts, safely shunting stray currents to ground. The result is ultra-clean, stable power transfer with significantly reduced noise and distortion—improving clarity and performance across your system.
These connectors are a highly effective, cost-conscious upgrade for anyone seeking cleaner, more detailed power delivery in a high-end audio setup.

Product Description
Lehmann Black Cube SE II – Precision Phono Stage for True Audiophiles
The Black Cube SE II builds on the acclaimed SE circuit, upgraded with superior sockets and an adjustable bass filter, allowing you to fine-tune your system to your personal listening preferences. Designed for maximum musical engagement, it delivers the sensation that your favorite recordings were crafted just for you, bringing instruments and vocals closer than ever.
Tailored for Every System
Compatible with nearly all MM and MC cartridges, the Black Cube SE II includes solder-free slots for custom impedance adjustments, plus an extra hardwired plug-in location for immediate flexibility. Optional matching resistors can be provided with your order at no extra cost, making it easy to optimize the phono stage for your system.
Audiophile-Grade Audio Circuitry
At its core, a high-precision passive RIAA filter network sits between two linear gain stages, built with surge-proof, narrow-tolerance polypropylene capacitors. This design preserves transients, dynamics, and timbres with exceptional clarity. Professional-grade input stages reduce noise while enhancing precision and power. Additional modules handle hum, high-frequency interference, and random voltage suppression, and the double-sided audio board ensures a low-interference signal path.
Dependable PWX Power Supply
The external PWX power supply features a custom toroidal transformer with static shielding, providing stable, safe, and powerful operation. Gold-plated Neutrik XLR connectors maintain secure connections, while shielded cables and mechanically damped aluminum housings minimize vibrations and interference.
Elegant Design
With a choice of silver, black, or chrome-plated front panels, the Black Cube SE II combines audiophile-grade performance with a refined aesthetic that looks as good in your HiFi rack as it sounds in your system.
Professional Endorsement
Known for its neutral, natural sound, Lehmann equipment is trusted by professional recording studios and music experts worldwide. The Black Cube SE II offers a high-fidelity listening experience that reveals every nuance in your favorite recordings.
Note: The sonic profile of Lehmann gear is perhaps the most neutral we can find. This brand is quite popular with our professional music/recording studio clients.

AUDIO
“Upgraded to the SE version by the PWX, it was definitely poking the fire again like almost no other phono pre in its price range. Merciless heavy rock by Vanilla Fudge or massive bigband attacks by Count Basie were just about to blaze through the listening room. Pimped in such a hot manner, the Lehmann Black Cube SE II is state-of-the-art.”

“This is a true audiophile phono stage and, partnered with equipment of equal quality, the results are remarkable. Indeed, the SE II is difficult to fault even compared to the competition in a much higher price bracket. The exceptionally low background noise allied to a fabulous rhythmic and tonal rendition makes it worthy of consideration for those seeking the most detail from their vinyl without having to make a hyperspace price jump.”
