HDPREAMP 65 years of innovation


Almost 20 years after the release of the mythical preamplifier Nagra PL-P in 1998, Nagra will introduce at the RMAF 2017 one of the most ambitious projects of its history, the HD PREAMP.

The Nagra R&D Department, served by ten skilled and specialized audio engineers, worked on this project for the past three years with the goal of creating the most revealing and engaging preamplifier in the world. The Audio engineers spared no expense or limitation developing electronics, mechanics, power supply and 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 just 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 pots 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 HDPREAMP has the best specifications ever achieved by any tube preamplifier, 160 dB of signal to noise and 5 Hz to 200kHz frequency response with perfect phase integrity. The impedance input is 50k oHm and the output impedance is 0.2 oHm so you can drive any amplifier on the market.

The HDPREAMP is able to reproduce a square wave at 16 Hz.

And the Sound !

20 times winner of BEST SOUND OF SHOW at high-end audio equipment conventions in the past year!

The HDPREAMP reproduces music with natural impressions, with 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..

Nagra’s room delivered not only the show’s best sound, but also one of the best-sounding demonstrations I’ve heard at any show.
