Product Description

Product Information

Lehmann Silver Phono Pre-Amp

With the Silver Cube Lehmann Audio's efforts in terms of technology, electronic parts and mechanics have lead to high-energy sound reproduction with excellent technical specifications and holographic soundstage delivery.

The Silver Cube not only provides maximum air and space with excellent soundstage depth and width, but also stunningly fast attack response, pace, timing, swing and dynamics... you will not be left untouched.

Visually, the massive milled aluminium case of the audio section impresses, while acting as a heatsink for the discrete zero-feedback Class-A FET output stage.
