HD DAC X: 37 Ultra-Low-Noise Power SuppliesHD DAC X uses ultra-fast silicon carbide rectifier diodes, ultra-low-noise voltage regulators, and a virtual battery made from a supercapacitor bank three times larger than the one in the HD PREAMP.
In total, 37 individually regulated ultra-low-noise power supplies feed the unit, with the digital section alone using 16 of them and a noise level 30 times lower than the original HD DAC.

HD DAC X: DSD 256 Internal ProcessingEvery input signal is converted into DSD 256 format at an 11.2 MHz sample rate, calculated by a high-performance FPGA under the timing of ultra-high precision, ultra-low jitter clocks.
Digital inputs cover AES-EBU, S/PDIF on both RCA and BNC, two Nagra-Link single-mode ST-1 optical inputs for future Nagra high-resolution sources, and a USB input built around a proprietary 8-core X-Mos chip design.

HD DAC X: Dual-Mono Analog Section With TubesThe analog section retains and improves the dual-mono topology proven in the original HD DAC, taking the D/A board’s output through a symmetrical current amplifier with a rise time around 1800 V/µS and no feedback or added gain.
After a stage of hand-built Nagra transformers, the impedance is lowered further by two NOS military JAN5963 tubes in a cathodyne output design, each with individually regulated filament voltage for very low self-noise.

HD DAC X: Home-Made Transformers From SwitzerlandVoltage gain comes entirely from a new generation of Nagra transformers, built exclusively in-house by Nagra’s specialised transformer technicians in Switzerland and subjected to stringent quality testing.
Nagra’s mechanical engineers also adapted the HD PREAMP’s vibration-free stand for HD DAC X, lowering microphonic resonance to a new level for the flagship converter.
