Three disciplines, one standard

The Phonolith was developed for a clear reality in the HiFi market: streaming dominates, vinyl is experiencing a strong comeback – other sources are fading into the background. Lehmannaudio responds to this with a device that serves precisely these two worlds in the highest quality. The Phonolith combines a highly flexible phono preamplifier, a powerful preamplifier, and a reference-level headphone amplifier in an unobtrusive form factor.

Phono stage with maximum adaptability

The integrated phono preamplifier offers extensive adjustment options for impedance and gain, making it suitable for practically all commercially available MM and MC cartridges. Four gain stages and selectable impedances, including a slot for a custom impedance, allow for precise adaptation to the respective system. Additionally, a switchable bass filter with multiple corner frequencies in the low-frequency range can provide tranquility if the setup or the vinyl material requires it.

Reference headphone amplifier from Lehmannaudio

Headphone amplifiers have always been one of Lehmannaudio's core competencies. The headphone output integrated into the Phonolith corresponds to the highest level currently offered by the manufacturer. Thanks to adjustable output gain, even power-hungry and insensitive headphones perform at their sonic best. This quality has been valued for years by internationally renowned sound engineers and mastering studios.

Preamplifier for modern setups

The preamplifier output of the Phonolith is capable of effortlessly driving even long cable runs. This allows the device to be flexibly combined with active loudspeakers or power amplifiers, such as the Lehmannaudio Stamp. The Phonolith is therefore ideal as a central control unit for a modern, minimalist high-end system.

Mechanical tranquility as the sonic basis

Both the audio section and the external PWX II LZ power supply stand (pre-assembled) on Lehmannaudio 3S equipment feet. These effectively convert disturbing resonances into heat and create the basis for a stable, quiet, and precise playback.

FAQ – Frequently Asked Questions about the Phonolith

Who is the Phonolith designed for?
The Phonolith is aimed at listeners who want to use vinyl and another source with maximum quality, consciously foregoing unnecessary features.

Which cartridges can I connect?
Thanks to variable impedances, four gain levels, and a selectable impedance slot, virtually all MM and MC systems can be operated.

Is the headphone output suitable for demanding headphones?
Yes. The adjustable output gain ensures that even insensitive headphones can unleash their full potential.

Can the Phonolith serve as a central preamplifier?
Yes. The pre-out easily drives long cables and is ideal for active speakers or power amplifiers.

Why an external power supply?
The separation of audio and power supply reduces interference and forms the basis for particularly quiet and precise playback.
