ATOM, STACKED

Atom DAC+ is built to pair with the enormously popular JDS Labs Atom Amp, now with even higher performance, both USB and TOSLINK inputs, and our latest upgradeable XMOS based firmware with UAC2 support and UAC1 fallback*. Atom DAC+'s subtle light ring glows when in use, automatically powers down during inactivity, and wakes up instantly and silently. A dedicated transformer ensures mains isolation. Stack Atom DAC+ with your Atom Amp and enjoy!

Features

MEMS OSCILLATOR

Atom DAC+ is clocked by 45/49MHz MEMS oscillators with ±25ppm frequency stability, delivering minimal jitter.

UPGRADEABLE FIRMWARE

Atom DAC+'s XMOS based firmware configures and manages all functionality, with DFU support for future updates.

UAC2 AND UAC1

Atom DAC+ supports up to 32/384kHz PCM over a custom XMOS XU208 based UAC2 engine. While we claim no measurable superiority of high sampling rates, UAC2 and ASIO support satisfy your pursuit of bitperfect listening. UAC1 mode is activated when using a UAC1 Fallback Cable.

EXTERNALLY POWERED

Atom DAC+ is powered by a perfected supply network, with an external AC transformer and 10 regulators that ensure consistent rail voltage and super low ripple.

AUTOMATIC STANDBY

Atom DAC+ automatically enters standby after 5 minutes of USB inactivity, powering down its light ring and D/A circuitry, and audio wakes up silently and instantly.

DIFFERENTIAL SUMMING I/V OUTPUT

Differential output of an ES9018K2M DAC is paired with our unique, DC coupled, precision tuned I/V converter with three stages per channel, or six NJM opamps in total.

Atom DAC+ for PS5

Easy to use, great quality. I had a little trouble with initial setup bc manual was not detailed enough. Customer suppoer, however, was responsive and immediately able to answer my question. I have been using for 8 months with zero issues.

Money well spent

I love it, sounds great, and does everything I need from it. My only complaint is that it is not in a metal enclosure, but I knew that going in. The light weight is noticeable however, but it is not enough of an issue that I would not recommend his amp/dac combo to others.

Very pleased. Wondering why it took me so long, lol. Hearing nuance and details I hadn’t heard before. I’d recommend your gear to everyone.

Holy explative, what a noticeable difference! My little PSBs were capable of so much more, and your DAC just brought it out. I think your tag line should be "you don't have to be an audiophile to hear the difference a great DAC makes".
