A New Chapter in a Legendary Lineage.
Some components make an impression before you've heard a single note. The Nagra PREAMP II-S is one of them.
The first component in Nagra's new Series II, the PREAMP II-S draws on more than seven decades of Swiss engineering and a lineage stretching back to the legendary PL-P tube preamplifier of 1998. It represents a significant evolution of the acclaimed Classic PREAMP, incorporating technologies and design philosophies developed for Nagra's extraordinary HD and Reference components.
At its heart is a new generation of vacuum tubes, selected for their remarkable transparency, low noise, and ability to communicate the smallest musical details. The presentation is unmistakably Nagra: expansive, dimensional, dynamically alive, and exceptionally natural. There's an effortless quality to the way music unfolds, with instruments occupying their own space against an extraordinarily quiet background.
And then there's the design. The iconic Nagra Modulometer returns, accompanied by a precision-machined rotary input selector, beautifully executed aluminum chassis, and an OLED display borrowed from the company's upper-tier electronics. It's a piece of industrial design that manages to feel both thoroughly modern and wonderfully timeless.
Beneath that elegant exterior, the engineering is equally considered. Advanced mechanical damping minimizes unwanted resonance, while an external power supply keeps electrical interference away from the sensitive audio circuitry. The result is a preamplifier capable of exceptional resolution without sacrificing warmth, body, or musical engagement.
The PREAMP II-S isn't simply a control center for an exceptional stereo system. It's an invitation to hear more deeply into the music you love.

- Liner Notes
The Return of the Modulometer™
The Series II brings back the legendary Nagra Modulometer™, derived from the iconic Nagra IV-S reel-to-reel recorder. This precision-engineered instrument allows accurate visual monitoring of left and right channel levels while reinforcing the unmistakable Nagra identity. The design philosophy of Series II focuses on sound quality above all, while maintaining a reasonable footprint suited to modern living spaces.
Mechanical Reference Legacy
Drawing from the mechanical expertise developed for the Reference turntable and Reference electronics, the PREAMP II-S benefits from advanced vibration control. A phenolic damping layer has been added beneath the aluminum top cover. Firmly glued and screwed in place, it ensures optimal control of mechanical resonances, contributing directly to the unit’s exceptional sonic stability and clarity.
HD Tube Technology
The PREAMP II-S is equipped with a new generation of tubes also used in the Classic Phono and the HD and Reference series. These tubes deliver enhanced transparency, improved micro-detail, and more realistic dynamic expression.
Power Supply Architecture
The PREAMP II-S is delivered as standard with the Nagra Compact PSU. Providing 12 V / 2 A, it supplies the preamplifier with an exceptionally clean and stable power source. Alternatively, the preamplifier can be ordered without a power supply for owners of a Nagra MPS or Classic PSU. The 12 V DC input uses the traditional LEMO connector, a hallmark of Nagra professional products for decades.
Sonic Signature
Owners of the Classic PREAMP who appreciate its accuracy without clinical character, wide and deep soundstage, lifelike dynamics, and exceptional silence will immediately recognize its musical DNA in the PREAMP II-S. The new model retains this signature while elevating performance in every aspect: greater transparency, improved spatial definition, enhanced dynamic expression, and an even deeper sense of musical flow.
