Lehmannaudio Linear SE mk II USB Transforms Digital Audio Into Pure Analogue Fidelity

Lehmannaudio Linear SE mk II USB headphone amplifier is a high-performance listening instrument that merges elite analogue engineering with audiophile-grade digital conversion. Designed for music lovers who demand transparency, precision, and emotional nuance from digital sources, this model incorporates a 384 kHz / 32-bit USB-DAC alongside the Linear SE mk II’s proven analogue design. Crafted in Germany with exceptional attention to detail, it offers a singular solution for high-resolution desktop or home audio systems.

Linear SE mk II USB Is a USB-DAC Headphone Amplifier With Ultra-High Resolution Support

Linear SE mk II USB integrates a native 384/32 USB-DAC for direct connectivity to laptops, music servers, or digital audio transports. This powerful digital input stage preserves every transient, harmonic, and microdynamic from studio-grade recordings, allowing listeners to unlock full high-resolution potential from lossless formats such as FLAC, ALAC, and DSD-converted PCM. With asynchronous transfer and low-jitter architecture, it delivers clean digital signals to the amplifier stage with pinpoint timing accuracy.

Linear SE mk II USB Converts Digital Sources With Exceptional Analogue Refinement

The USB-DAC module in the Linear SE mk II doesn't simply decode — it elevates. It prioritises USB input over the analogue line-in, ensuring seamless switching and minimised signal degradation. By channeling the converted signal into the Low-Z Copper analogue board, it enables an uncompromised transition into the Linear SE’s discrete Class A amplification path, capturing the full detail and expressiveness of the original performance.

Linear SE mk II USB Drives All Dynamic Headphones With Precision and Headroom

Engineered for compatibility with all dynamic headphones, the Linear SE mk II USB features adjustable gain settings up to 20 dB, selectable via DIP switches. From low-impedance monitoring headphones to high-impedance audiophile flagships, this amplifier ensures perfect synergy. The 400 mW/60-ohm output power and 5-ohm output impedance guarantee dynamic control, spatial separation, and consistent frequency response across headphone types.

Linear SE mk II USB Serves as a Digital-Analogue Preamp for Complete System Integration

This amplifier isn’t limited to headphone use—its 60-ohm pre-out transforms it into a reference-class USB DAC preamplifier. Whether driving active nearfields, a stereo power amp, or feeding a reference audio interface, it maintains tonal purity and low signal loss. Its gold-plated RCA outputs, Teflon-insulated for dielectric stability, ensure an unfettered signal path from DAC to destination.

Linear SE mk II USB Uses Audiophile Components Like Mundorf Capacitors and Mogami Wiring

Premium parts distinguish the Linear SE mk II USB from generic desktop audio gear. High-spec Mundorf capacitors, chosen for their low ESR and musical coherence, feature in both power and signal paths. These are paired with Mogami internal cables, widely regarded in studio environments for their transparency and low capacitance. The result is a sonically revealing platform that highlights textural subtleties and harmonic realism.

Linear SE mk II USB Offers Two Gold-Plated Neutrik Headphone Outputs for Flexible Use

Dual front-mounted headphone outputs allow simultaneous listening or A/B headphone testing — ideal for audio professionals and discerning enthusiasts. Fitted with gold-plated Neutrik jacks, these sockets maintain physical durability and low contact resistance, delivering consistent output even during extended, high-volume listening sessions.

Linear SE mk II USB Offers Customisable Aesthetics to Match Listening Environments

With an emphasis on form as well as function, the Linear SE mk II USB offers modular housing finishes, faceplate variations, LED colours, and 3S Device Feet in silver or black. Whether installed in a sleek workstation, dedicated listening room or modern hi-fi stack, its minimalist industrial design adapts seamlessly. Optional finishes include chrome, brushed black aluminium, and silk flat silver — each bringing a distinctive visual identity to this precision-crafted machine.

Linear SE mk II USB Is Award-Winning and Studio-Grade in Both Design and Execution

Recognised by stereoplay and i-fidelity.net as a top-tier headphone amplifier, the USB-equipped Linear SE mk II extends that pedigree into the digital realm. Its conversion path is tuned to professional mastering standards, while its amplification stage preserves dynamics, depth, and tonal realism. This version is ideal for music professionals, hi-fi enthusiasts, and digital audio purists seeking a no-compromise USB playback chain.

Linear SE mk II USB Brings Digital Music to Life With Analogue Warmth and Detail

At the intersection of digital precision and analogue soul, the Lehmannaudio Linear SE mk II USB offers a playback experience that is both technically immaculate and emotionally rich. Whether driving flagship dynamic headphones, feeding powered monitors, or decoding your high-resolution digital archive, it provides a transparent, musical, and thoroughly refined signal path from USB port to ear.
