Back in 1992, Nagra was the first audio manufacturer to release a high-definition digital recorder the Nagra D (24 bit, 96 kHz). Originally launched in 2018, the Nagra HD DAC X drew upon this innovative technology.
The release of the Nagra Reference turntable and cartridge, followed by the Nagra HD PHONO, set new standards for analog reproduction in the same way as our own reel-to-reel player, the marvelous Nagra IV-S, had when it was launched. Now it was time for us to focus once again on the digital world and benefit from what we had learned with the new Nagra Streamer.
Nagra intensive research and painstaking extensive listening sessions resulted in essential component changes in the audio unit, including custom made capacitors. We created a new generation of high voltage power supplies inside the audio signal unit (generating the 200 V DC grid tension). For the power supplies, we added super-cap capacity. The Reference DAC was given dual chassis power supplies, one dedicated to the audio signal section and one dedicated to the digital section, as well as all controls and relay switching, including home automation*.
* Although the Reference PREAMP (as well as the future DAC and PHONO) can run on a single power supply, the sound is more spectacular and life-like with two PSUs. Starting with one PSU will give customers an easy upgrade path and allow them to add a second one for unrivaled performance at some time in the future.
