Product Details

The DirectStream DAC is our reference standard D to A converter. It is unlike any standard chip-based DAC, and has received countless awards, worldwide.

DirectStream is one of the most remarkable DACS ever built as all the major reviewers agree. Hand written, discrete, perfection based conversion that uncovers all the missing information hiding in your digital audio media. CD’s, streaming audio, high-resolution PCM or DSD based media are expertly upsampled in the DirectStream to twenty times DSD rate and output as pure analog directly into your amplifier or preamplifier. There has never been a better sounding DAC at anywhere close to the price of DirectStream. It is the first choice of thousands of critical listeners worldwide, and with its ability to accept our free Operating System upgrades, will never become obsolete.

DESIGN

DirectStream converts every input signal, both PCM and DSD, to single-bit, high sample rate 20X DSD signal. Use of a FPGA rather than an off the shelf DAC chip provides immense processing power, resulting in complete lack of digital glare, and allows the owner to download OS updates as they are released.

APPLICATION

DirectStream is the heart of a reference quality digital audio based system. It handles all PCM sources up to 352.8 kHz, and DSD 64 and 128 (USB and I²S) and DSD256 (I²S only, with the Sunlight OS). Its zero-loss digital volume control allows it to be used as a preamplifier, directly feeding a power amp. Include the Network Bridge to stream Qobuz, Tidal, and Spotify. Roon ready.
