Some components don’t just improve a system — they change your relationship with music. The Nagra PREAMP II-S is one of those rare pieces: the first model in Nagra’s new Series II, created to deliver unmistakable Nagra purity, control and musical truth in a beautifully compact, purposeful preamplifier. From the first minutes, it’s the ease that gets you — deeper silence, richer colour, and a sense of flow that turns “one track” into the whole album.
A new Nagra chapter — made for music lovers
Series II is not a minor update. It’s a fresh platform designed between the Classic and HD ranges, taking proven Nagra thinking and pushing it into a new space: more direct, more focused, and built to bring out the emotional heart of recordings without ever sounding forced or “hi-fi”.
The Modulometer™ returns — and it feels like coming home
One glance and you know it’s Nagra. The iconic Modulometer™, inspired by the legendary IV-S recorder, isn’t just beautiful — it’s a symbol of Nagra’s professional roots, where precision and musical integrity are everything. It makes the PREAMP II-S feel like a serious instrument, not just another component.
Reference-inspired engineering, real-world magic
Borrowing mechanical know-how from Nagra’s top Reference developments, the PREAMP II-S uses advanced resonance control to sharpen focus and stability. In listening terms: a more solid soundstage, purer tone, and that addictive combination of speed, texture, and effortless dynamics that makes voices and instruments feel startlingly real.
