D100 24-bit Stereo DAC

The D100 stereo digital to analog converter is the sum of our quest for true audio fidelity. By combining the highest quality components with a solid scientific foundation, the D100 produces music that is free of coloration and true to the source.
Digital audio is processed by a Wolfson WM8804 which provides excellent jitter rejection. The signal is then fed to a pair of Burr-Brown PCM1794A chips operating in mono mode for the greatest dynamic range, highest signal-to-noise ratio, and complete channel separation.
The majority of high-end audio DACs utilize an active analog output stage comprised of op-amps, feedback circuitry, and additional filters. In contrast the D100 output stage is entirely passive and consists of 0.1% resistors with Jensen JT-11-EMCF transformers—the output is a pure audio signal.
The D100 Mk2 features new Jensen transformers that provide an additional 6dB of gain while maintaining the same sonic characteristic of the D100.

The sound? Pure bliss.
A clean uncolored sound that is bit-perfect from its source.

..."clean and natural."
"Blackbird" sounded with the D100 as good as I've heard it.
