Nagra HD PREAMP HV Edition
Almost 20 years after the release of the mythical preamplifier Nagra PL-P in 1998, Nagra releases one of the most ambitious projects in its history, the HD PREAMP. A perfect companion to the HD AMP, the HD PREAMP features a unique patented technology for volume control based on high-quality in-house made transformers and is powered by an external bank of super-caps, dual-mono, tube signal-path without feedback.
Power Supply included.

Nagra HD PREAMP (HV Edition)
The Nagra R&D Department, served by ten skilled and specialized audio engineers, worked on this project for three years with the goal of creating the most revealing and engaging preamplifier in the world. The audio engineers spared no expense and accepted no limitation in developing electronics, mechanics, power supply or in addressing thermal and vibration issues. Each stage of the design also included extensive listening sessions. The result is a striking product in terms of appearance, specification and performance. It will reshape the expectation you may have of what a preamplifier will add to your whole set-up, sources and amplifiers.
The volume control is a patent-pending technology that allows perfect level matching with a much more transparent sound compared to potentiometers and switch resistor technology, because there is no attenuation of the input signal, just an automatic selection of a tap on the Nagra custom output transformer.
The newly developed SuperCapacitor power supply is a new technology which combines the very low noise of a battery with the high current capability of the best linear power supplies.
The audio engineers created a super vibration-free stand to lower the microphonic resonances to a new level.
The HD PREAMP has the best specifications ever achieved by any tube preamplifier, a floor noise lower than -160 dB and 5 Hz to 200kHz frequency response with perfect phase integrity. The impedance input is 50 k Ohm and the output impedance is as low as 0.2 Ohm so that you can drive any amplifier on the market.
The HD PREAMP is able to accurately reproduce a square wave at 16 Hz.
And the sound !
The HD PREAMP reproduces music giving a natural impression, full spectrum bandwidth and extreme stability.
It also produces a precise 3D holographic soundstage. It is very difficult to express the impact of this design as we didn’t think it was possible to achieve such an unbelievable result.
Pure emotion !
HD LINE
Inspired by our decades of designing top high-end equipment, the HD – for High Definition – range is the embodiment of Nagra’s design, engineering and manufacturing prowess. When we initiated the HD Line our vision was to focus on performance and have no consideration for dimensions, cost or development time. The results are unique products that make use of revolutionary technologies (some patented) to provide a sound that will surpass the expectations of the most demanding music lover.
