Nagra is announcing the future relese of the HD PREAMP, to complement the HD Line, this Fall. The HD PREAMP will feature the legendary PL-P modulometer to celebrate the Nagra PL-P 20th anniversary.

The Swiss company announces it is designing a new preamplifier to complement the HD range, to be called simply the HD PREAMP and released this fall.  

Until the HD PREAMP is available for demonstration this summer, Nagra will showcase a system built around the HD DAC and HD AMP. A similar set-up was demonstrated to great acclaim at the CES 2017 in Las Vegas.

World announcement of the NAGRA HD PREAMP, twenty years after the NAGRA PL-P preamplifier was released on to the high-end market.

In 1997, NAGRA introduced its very first high-end consumer product after more than 40 years of continuous success in the professional recording market. The PL-P preamplifier was a class A triode-based line and phono preamplifier that immediately set new standards in sound reproduction. It became a reference all over the world and received awards from Stereophile (USA) and Stereo Sound (Japan) magazines among many others.

In Munich, Audio Technology Switzerland, the company that designs and builds Nagra electronics, unveils its NAGRA HD PREAMP project. The HD PREAMP has been created as a perfect partner for the HD DAC and HD AMP.

In many respects, the HD PREAMP’s design started from a blank page. Every aspect and step in the design process involved research to find the most elegant solution to accurately and faithfully convey the music from the source to the amplifier. As a result, the HD PREAMP - also a tube design  - includes several patent-pending technologies that take the music listening experience to new heights. 

Nagra’s unique approach to designing audio products draws on 65 years of experience in the field, a large and skilled R&D group as well as extensive listening sessions. This frequently results in a very organic and natural sound. The unit is tube based, dual-mono, with separate super-cap power supply. It features high end custom made components as well as Nagra in-house audio transformers. 

As a tribute to Nagra legendary recorders and PL-P preamplifier, the HD PREAMP will feature the mythical modulometer (see picture). The modulometer is a custom made measuring unit that differs from traditional Vu-meter, as modulometers are faster and more accurate.

As is to be expected with such high-quality electronics, the sophisticated power supply will be located in a separate chassis. Like the audio circuit, it uses ultra-high quality components that are specified for extreme applications. Just as the PL-P made use of batteries to isolate the unit from external interferences, the HD PREAMP’s power supply uses a unique virtual battery technology - built around super-caps - that provides superior results compared to a conventional battery without the inconvenience of dealing with charging time and battery life. Consequently, the noise floor level at the preamplifier reaches uncharted territories; it is the lowest ever measured on a NAGRA product. 

The HD PREAMP’s chassis construction and power supply ensures that the unit is free from the influence of external disturbances (vibration and electrical interference) and will drastically reduce mechanical resonances. As a result, the HD PREAMP promises to set new standards for preamplification as did the PL-P twenty years ago.

The NAGRA HD PREAMP is due for release in fall 2017.
