Lehmann Audio Black Cube Linear USB II headphone amplifier and DAC for users who also want to play high-resolution audio files from a PC or Laptop.
Analogue Circuitry
Linear USB II is distinguished by its completely revised analogue circuitry. The discrete Class A output stage grants an open and natural sound, high-grade Low-Z Copper technology across the PCB circuitry and specially selected components – like the oversized internal power supply and low-loss MKP precision capacitors – this delivers physical, punchy lows and startling resolution in an open and natural soundstage over the entire frequency bandwidth, so headphones fulfil their highest potential.
System Matching
This headphone amp features three Gain settings up-to 20dB and also benefits from two Neutrik headphone sockets with gold-plated contacts, which can be used simultaneously. The Left headphone output mutes the rear line-level RCA output when a headphone is connected. There is also an additional analogue RCA input for connecting more traditional line-level sources, but it’s main appeal is in the high-resolution USB digital audio input.
Auto-Detect Signals
The Linear USB II automatically detects any incoming USB audio data stream, without the need for an input selector switch. The technology employed utilises an ESS Sabre K2M DAC chip, capable of 32-bit / 384kHz playback and DSD support (DoP) for playback of very high-resolution digital audio files.
Reference Class
The Linear USB II works well as a streaming pre-amplifier for a full hi-fi system. With the auto-input detection and sophisticated internal layout, it is a simple yet premium solution that can easily drive long cables toward a power amplifier or active speakers. This is a truly a reference class pre-amplifier for all dynamic headphones employing a sturdy metal housing with SSC damping feet, for effective decoupling from environmental factors, the aluminium faceplate is available in Black, Silver or Chrome.
