Magnetostat Se is a reference valve line stage whose amplification and coupling strategy is centred on custom magnetic devices. NAT combines a zero-feedback triode circuit with transformer-based signal transfer to reduce the number of conventional passive elements encountered by the music signal.

Its high-energy power supply, extensive regulation and separated functional sections are designed to maintain dynamic stability while keeping noise low. Balanced and single-ended interfaces allow the preamplifier to work with a broad range of sources and power amplifiers.

The chassis uses thick machined aluminium, premium connectors and hand-assembled internal wiring. Component selection focuses on close-tolerance parts and long-life valves suitable for sustained reference-system use.
