Digital Meets High-End: A New Dimension of Musical Enjoyment

Since the first Linear revolutionized the headphone world in 2004, it has been considered a reference among audiophile amplifiers. With the Linear D mk II, Lehmannaudio now goes a significant step further: A refined ESS Sabre DAC, a completely new Low-Z analog board, and high-quality components ensure strikingly clear, dynamic, and spatial reproduction.
From the very first note, the incredible purity of the playback is impressive – the finest details emerge without sounding harsh.

Maximum Convenience – Fully Automatic

The Linear D mk II automatically detects digital signals, selects the active input, and elegantly switches to analog operation if no digital signal is present.
No switching, no incorrect operation – just listen to music.
Two digital inputs (TOSLINK, S/PDIF) and one analog RCA input make it the perfect control center for streamers, CD players, and computers.

Latest Generation Sabre DAC – Music as It's Meant to Be

The integrated ESS Sabre K2M DAC guarantees:

• 24-bit resolution
• Sampling rates up to 192 kHz
• Extremely low distortion
• Perfect impulse response thanks to Silver Mica analog filter
• Musically fluid, natural reproduction
  Whether HiRes files, streaming, or CD – the Linear D mk II converts every digital source with Lehmannaudio quality.

New Low-Z Analog Board – Spectacular Dynamics and Precision

The refined analog board offers:

• Lowest impedances for maximum signal fidelity
• Audibly increased dynamics
• Deeper, more stable spatial imaging
• Faster, cleaner impulse response
  This technology comes directly from Lehmannaudio's high-end models and significantly elevates the Linear D mk II's sound quality above its predecessor.

As a Headphone Amplifier: A Class of Its Own

The Linear D mk II drives even the most demanding headphones with impressive ease.
Highlights:

• Discrete Class-A output stage without global negative feedback
• Three gain stages for perfect adjustment
• Two parallel headphone outputs without quality loss
  It offers powerful bass control, silky highs, and a holographic soundstage.

As a Preamplifier: True High-End for Active Speakers

Thanks to its high-quality pre-out, the Linear D mk II is an excellent purist streaming preamplifier.
It makes active speakers significantly more precise, powerful, and spatial – a true upgrade for any system.
