“All in all, this is a great amplifier! It is extremely easy to set up and sounds good with little or no tweaking. It is about enjoying the music and not a finicky or touchy piece of gear. It is very cohesive and the tonality is excellent and very well integrated from highs to lows.”
About EAR
EAR Yoshino (formerly Esoteric Audio Research) was founded by legendary designer Tim de Paravicini, whose name has been synonymous with high-fidelity electronics since the 1970s. His groundbreaking circuit designs have shaped not only EAR components, but also products for many of the world’s most respected audio manufacturers. Several of his creations remain highly sought after decades after their introduction — a testament to their enduring performance and musical integrity.
Beyond the world of home audio, Tim de Paravicini made significant contributions to professional recording and mastering. His tape machines, microphones, and electronics have been used by artists such as Pink Floyd and Lenny Kravitz, as well as acclaimed labels including Water Lily Acoustics. Renowned engineers like Robert Ludwig, Joe Gastwirt, and James Guthrie have relied on his designs. London’s prestigious The Exchange employs complete playback chains built around EAR electronics, while Mobile Fidelity Sound Lab has utilized his LP cutting and tape playback systems.
EAR amplifiers are celebrated for their ability to reproduce music with exceptional purity and accuracy, conveying the original signal with remarkable transparency. Tim de Paravicini’s pioneering research into ultrasonic resonances, transient response, and the subjective perception of distortion helped bridge the gap between technical measurements and real-world listening experience.
The result is amplification widely regarded by enthusiasts and professionals alike for its precision, musicality, and long-term listening satisfaction — a legacy that continues to define the EAR name today.

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.

“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.”
