The Nagra HD DAC X represents the pinnacle of Nagra’s digital audio engineering, offering a “Tube DAC Package” in a two-chassis, ultra high-end system. Handcrafted in Switzerland, it comprises a dedicated audio device and a highly sophisticated external power supply, designed to deliver an analog-like listening experience from digital sources.

The HD DAC X converts all incoming digital signals to DSD 256 (11.2 MHz) via a proprietary FPGA-based engine. Its acclaimed analog output stage features two meticulously selected, military-grade NOS JAN5963 vacuum tubes, complemented by custom, hand-wound Nagra transformers, ensuring pure, uncolored sound. The accompanying external power supply is a masterwork of low-noise design, employing a massive supercapacitor bank and 37 individual regulated power supplies for unparalleled stability.

With comprehensive digital inputs including USB, AES/EBU, and Nagra-Link, the HD DAC X supports PCM up to 384 kHz and DSD 256. Housed in Nagra’s iconic, precision-machined chassis with a signature modulometer, the HD DAC X is renowned for its extraordinary transparency, dynamics, rich texture, and ability to render music with breathtaking realism and emotional depth.

Nagra Tube DAC Features

DESIGN
Extended chassis common to the CLASSIC range allows a greater number of components to be used compared to the Nagra JAZZ. This allows greater filtering of the internal power supplies for an improved listening experience. This design philosophy was first seen on the HD DAC and inspires the entire CLASSIC range.

ELECTRONICS
Bespoke polypropylene capacitors created especially for the CLASSIC PREAMP are used for decoupling and interstage to deliver exceptional performance.

- Wide frequency response and linear phase response provided by no-compromise design and high quality custom-made components.
- Separate multiple ultra low-noise right and left channel power supplies create a larger and more realistic soundstage.
- High-quality headphones amplifier circuit is the same as that employed by the Nagra HD DAC.

CONNECTIVITY
1 x XLR and 4 x RCA inputs enable the CLASSIC PREAMP to be connected to a variety of sources.
2 x XLR and 1 x RCA outputs allow the CLASSIC PREAMP to be connected to two power amps if required for a monobloc solution.
A true bypass XLR connector allows the machine to be hooked up to a high-end home cinema to benefit from a power amp downstream and provide a neat cabling solution.

Optional input and output transformers are available separately to create a fully symmetrical floating signal that will further enhance performance. These transformers are hand-wound in-house by Nagra in order to meeting the exacting standards of the design brief.

POWER SUPPLY
On-board internal power-supply allows direct connection to the mains, a feature shared with the CLASSIC DAC. This solution, which obviates the need for the external Nagra ACPS II power supply delivered separately with other Nagra units nonetheless produces superior performance. Should the customer desire, the CLASSIC PREAMP can be powered by Nagra’s dedicated Classic PSU power supply via the 12 V DC Lemo connector on the rear panel to provide additional performance gains.

USER-FRIENDLY DESIGN
Front panel with LCD screen, similar to the Nagra CLASSIC DAC so that each input can be named. An intuitive menu allows access to custom settings as well as operating time. All functions are accessible via a provided remote.

- Traditional Nagra Modulometer showing the output level.
- Output gain is switchable between 0 and 12 dB via a switch on the front panel to achieve optimal gain whatever the nature of the source.

Same dimensions as the other elements in the Nagra CLASSIC range allowing for neat and aesthetic stacking in the building of a complete Nagra system from various components.

Classic PSU Features

PERFORMANCE
The Classic PSU is a very technically advanced product that can be seen as a compact HD PREAMP power supply. It features carbide silicon diodes, extremely fast diodes without recovery time. They allow a totally smooth rectification. It also includes cascades of silent regulators to offer a perfectly stable DC current for the Classic Line to operate with.

The Classic PSU can be used with the CD range of products, VPS phono stage, JAZZ, Melody and the latest Classic DAC, Classic PREAMP, HD DAC and TUBE DAC. It will revitalize any Nagra devices and allow them to express their full potential.
