The Nagra HD DAC converts digital signals to analog with exceptional fidelity, preserving the original sound without any impurities. Its design features DSD 2X (Direct Stream Digital 128) circuits, achieving a resolution 128 times higher than standard CDs and twice that of SACDs.

The analog section eliminates traditional steep slope filters, maintaining transients and harmonics for a natural sound. Key components include ultra-high performance drivers, hand-wound transformers, and a tube-driven output stage. It has 25 precision ultra-low-noise power supplies, with separate external supplies for digital and analog sections to ensure purity.

With extensive connectivity options, the HD DAC is versatile for both domestic and professional systems, and it excels in computer setups via its audio USB input, supporting signals up to DSD 128 from PCs and Macs.
