Leema Neutron Pre-Amplifier

The Neutron Pre Amplifier by Leema stands out as an exemplary component that fulfils the core functions of a great pre-amp with precision and reliability. Its primary strength lies in transparency, delivering an unaltered representation of the audio signal. The incorporation of both analogue and digital inputs provides users with modern-day flexibility, ensuring compatibility with a wide range of audio sources. The classic circuit design, meticulously implemented on the board, is instrumental in achieving reference-standard levels of cross-talk, contributing significantly to the overall quietness of the design. This commitment to detail pays off in a pre-amplifier that maintains a low noise floor, allowing the listener to experience subtle nuances with clarity.

The Neutron's capability to uncover often-hidden details adds an extra layer to the listening experience, fostering total engagement with the artist's work. Notably, the pre-amplifier features an exceptionally high-quality MM/MC phono stage, catering to vinyl enthusiasts with a discerning ear. The physical design reflects durability and a sleek aesthetic, featuring a solid aluminium machined front panel and custom machine aluminium control dials. With four RCA inputs, one XLR balanced input, three optical, and three coaxial inputs, the Neutron provides versatile connectivity options. The inclusion of an asynchronous USB connection at 24bit/192kHz PCM further enhances its adaptability to various digital sources.

Enhancing its functionality, the Neutron incorporates fixed-level record outputs and two dedicated sub-woofer outputs, catering to diverse audio setups. Components like the high-end Burr Brown analogue volume control and a dedicated onboard headphone amplifier contribute to its comprehensive design. The pre-amplifier also features ultra-high-performance switchable MM/MC phono stage, balanced and RCA preamp outputs, re-nameable inputs, and a 12V power trigger line. Crafted and manufactured in the UK, the Neutron is available in brushed black or silver finishes.
