Key Features of the Phasemation EA-1500
Advanced Sound Quality Inspired by Flagship Technology
The Phasemation EA-1500 Phono Equalizer Amplifier incorporates design concepts developed for the flagship Phasemation EA-2000 Phono Equalizer Amplifier. Technologies such as the LCR-type equalization circuit and carefully shielded transformer structures contribute to a refined, highly detailed sound presentation that reflects Phasemation’s long-standing expertise in phono amplification.
Vacuum Tube Design with Non-NFB Circuitry
Built around a high-voltage vacuum tube architecture, the EA-1500 delivers impressive dynamic range and natural musical expression. The non-negative feedback (Non-NFB) circuit design helps maintain fast signal response and preserves the subtle nuances of vinyl playback.
Step-Up Transformer for MC Cartridges
For moving-coil cartridges, the EA-1500 features a specially redesigned step-up transformer derived from the Phasemation EA-1200 Phono Equalizer Amplifier platform. Its newly refined windings use highly regarded PC-TripleC wire, helping achieve excellent signal integrity and compatibility with a wide variety of cartridges.
Support for Modern Optical Cartridges
In addition to traditional MM and MC cartridges, the EA-1500 is designed to work with newer optical cartridge systems. A dedicated transformer provides stable power for optical cartridge operation without interfering with the main phono circuitry. An XLR input is also included, allowing optical cartridge outputs to connect using standard balanced MC cables.
Dual-Chassis Design with Dedicated Power Supply
The EA-1500 features a separate power supply chassis designed to minimize interference and improve sonic purity. Inside, a three-transformer configuration powers the system, including independent transformers for the left and right channels. A vacuum tube rectifier using 5U4GB tubes helps deliver clean power with reduced switching noise compared to typical semiconductor rectifiers.
Balanced and Unbalanced Connectivity
For system flexibility, the EA-1500 includes both balanced (XLR) and unbalanced (RCA) inputs and outputs. Premium NEUTRIK XLR connectors and gold-plated RCA terminals are used throughout to support reliable connections and high-quality signal transfer. Balanced and unbalanced outputs can also be used simultaneously.
Carefully Tuned Mechanical Construction
The chassis design and structural components have been acoustically optimized to minimize vibration. Hybrid metal insulators help reduce resonance, while the 1.6 mm thick top cover features a low-dielectric coating to reduce magnetic distortion and maintain signal purity.
Premium Components for High-Fidelity Playback
Gold-plated connectors and high-quality relay contacts are used throughout the unit to help ensure stable performance and accurate audio reproduction.

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.

Reviews
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.”
