The HD DAC X is a step forward from the world-acclaimed Nagra HD DAC. It includes many of the technological advances from the HD PREAMP.

The result is a lifelike sound with warmth, texture, extreme dynamics and extended frequency response beyond what has ever been achieved by other D/A converters.

The power supply is extremely sophisticated, using ultra-fast silicon carbide rectifier diodes, ultra-low-noise voltage regulators, and a virtual battery made up of a supercapacitor bank three times larger than the one in the HD Preamp. The new HD DAC X includes no fewer than 37 regulated ultra-low-noise individual power supplies.

The analog section is quite unique. The proven solutions adopted for the Nagra HD DAC have been retained and improved. Like the HD PREAMP, it uses a dual-mono topology. The analog signal coming out of the D/A board is taken to a symmetrical current amplifier that dramatically lowers its impedance. This unique stage reaches astonishing performance levels with a rise time in the order of 1800 V / µS into the 28 H inductive load of the inter-stage transformers. It makes no use of feedback nor does it provide any gain.
