Lehmann Audio Black Cube SE Phono Preamplifier

Black Cube SE Phono Preamplifier Delivers Studio-Grade Vinyl Playback

Black Cube SE Phono Preamplifier is a high-performance analogue audio component engineered for audiophiles seeking reference-grade sound reproduction from vinyl. As an enhanced edition of Lehmann Audio’s acclaimed Black Cube, the SE variant integrates the potent PWX power supply to deliver exceptional dynamics, clarity, and emotional realism across the entire frequency spectrum.

Black Cube SE Offers High-Fidelity Signal Amplification with Studio Precision

Black Cube SE Phono Preamplifier is a low-noise, high-gain analogue preamp designed to accommodate both moving magnet (MM) and moving coil (MC) cartridges with outstanding linearity. Its circuitry uses input stages derived from upper-tier microphone preamps and mixing consoles, ensuring ultra-low distortion and expansive dynamic headroom.

The four selectable gain settings—36 dB, 46 dB, 56 dB, and 66 dB—make this premium phono stage compatible with a wide array of cartridge output levels. Whether you're using high-output MM cartridges or low-output MC types, the Black Cube SE adapts with precision, offering 775 mV output sensitivity and signal-to-noise ratios of 71 dB (MM) and 63 dB (MC) to maintain signal integrity without added grain or coloration.

PWX Power Supply Enables Powerful and Relaxed Sonic Delivery

Black Cube SE with PWX Power Supply enhances sonic authority through a dedicated, shielded, and compact external power module. This power unit, linked via gold-plated Neutrik XLR connectors, feeds the audio circuitry with ultra-clean, isolated current, minimising interference and microphonic distortion. The result is a more spatially articulate soundstage, deeper bass impact, and an emotionally expressive midrange—ideal for revealing the nuances in vocal timbres and instrumental textures.

The low power consumption (<3 W) also ensures thermal stability and longevity, while the power section's separate aluminium enclosure further reduces electromagnetic interaction with the audio signal path.

Precision RIAA Equalisation Ensures Accurate Frequency Response

Black Cube SE Phono Preamplifier incorporates a passive RIAA filter network constructed with premium polypropylene film capacitors. This segment sits between two linear gain stages, ensuring ideal phase coherence and minimal deviation from the RIAA curve. The transient response benefits directly from this architectural layout, preserving rhythm and attack even in complex passages of orchestral or jazz recordings.

Enhanced channel separation exceeding 85 dB at 10 kHz reinforces stereo imaging, allowing for exact localisation of instruments within the soundstage. Meanwhile, the 50 Hz bass filter (6 dB/oct) effectively minimises low-frequency rumble from warped records or mechanical vibrations.

Customisable Impedance Loading Enables Cartridge Tailoring

Lehmann Audio Black Cube SE introduces advanced cartridge-matching flexibility through two user-configurable loading features: a solder-free custom impedance slot and an additional hardwire plug-in location. This thoughtful design supports precision matching for esoteric MC cartridges, including those requiring non-standard impedance values beyond the default 47kΩ, 1kΩ, and 100Ω options.

Such load adaptability enables critical listeners and analogue purists to fine-tune tonal balance, damping behaviour, and overall system synergy with meticulous control.

Compact Aluminium Enclosures Maximise Placement Versatility and Minimise Interference

Black Cube SE’s chassis is crafted from non-magnetic aluminium, shielding sensitive internal components from environmental electromagnetic fields. The mechanically damped top covers reduce resonance and microphony, ensuring clarity even at high playback volumes or in vibration-prone setups.

With an audio section measuring 113 mm x 108 mm x 45 mm and a power supply measuring 92 mm x 232 mm x 45 mm, the system is space-efficient without compromising acoustic performance. The 0.4 kg audio section and 1.0 kg power supply contribute to the unit’s robust, resonance-damped physical presence, ideal for shelf-top or rack-mounted installations.

Award-Winning Design Recognised by Audio Professionals

Lehmann Audio Black Cube SE has earned accolades such as image hifi award, LP's Best of 10 Years, and SoundStage! Network’s Hall of Fame and Reviewers' Choice awards. These distinctions underscore its lasting impact in the audiophile and professional mastering communities.

Built in Germany with meticulous attention to design and signal integrity, this reference phono stage delivers an immersive analogue experience that reveals the full expressive potential of your vinyl collection.
