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!

 

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 fallback* is activated when using a USB 1.1 hub or isolator.

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 15 minutes of 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.

Excellent Dac

The internals are excellent for the value but the outer build is subpar and feels very cheap, JDS made a poor option on skimping out on build material quality, would have paid a bit more for something higher quality. Overall this is an excellent choice in comparison to the Schiit stack for Canadians. Buying from deskhero has given me an excellent option for a desktop amp/dac stack without having to pay insane shipping fees and import fees from out of country. Even Amazon has very limited budget options. Currently using this with my HD660S headphones

Excellent value and no border shenanigans

Thanks to Deskhero for making this available and at a reasonable price for Canadians. It arrived quickly enough and it was recognized instantly on my Linux kernel 5.10. Without anything to compare it to, I'll just say that the sound quality of the DAC is very pleasing. Movies and music sound better compared to the DAC that I had before; Very warm and laid back.

Clean sound out of the box

I'm using a late 2012 iMac and the DAC was recognized instantly.

I connected it to an old pair of powered speakers without digital inputs.

The Atom DAC+ really added additional finesse to my listening experience in comparison to having the speakers directly plugged in the line out of the iMac.

Thank you Deskhero for being an official distributor of JDS Labs! Thanks to you, I don't have to play the import duties roulette!
