THE VERDICT
THX's portable DAC/amp delivers dynamic and spatially precise sound. Paired with the right headphones, it's a compelling option for portable high-res playback

Home theater enthusiasts know THX for its certification program, an initiative responsible for the familiar logo emblazoned on all manner of gear for nearly three decades, along with the Deep Note trailer heard in certified movie theaters and on home video releases. Surprisingly, the company never released its own "THX" product, a situation that now changes with the arrival of the THX Onyx portable DAC/headphone amplifier.

THE VERDICT
PS Audio’s new Sprout 100 is a worthy option for anyone seeking a compact integrated amplifier/DAC that also handles vinyl playback.

The original PS Audio Sprout integrated amplifier/DAC was noted as being part of a new trend of ultra-compact ampDACs when Sound & Vision reviewed it back in 2015. We’ve since tested similar models from Elac and Teac, though it was the Sprout that most grabbed our attention due to its moving magnet phono stage—a feature those other models happen to lack.

THE VERDICT
This full-featured budget amp/DAC can get the best out of most headphones, especially in the all-important presence region.

If you’re looking for a USB amp/DAC to juice your headphones, you might assume that a couple hundred bucks would buy nothing more than a stick amp, one of those compact dongles that extends straight out from your computer’s USB port. We live in the golden age of the stick amp, and I’m sure not knocking ’em. But what if the same money can buy something with a little more real estate for circuitry and the always vital power supply, offering better than 96-kilohertz/24-bit resolution, DSD, MQA, and two headphone outputs with different gains, one for demanding ’phones and one for more efficient ones (including in-ear monitors, aka IEMs)? Of course, you must read on.

THE VERDICT
The Korg DS-DAC-10R lets you move your music from LP records into state-of-the-art high-resolution PCM or DSD files, all while retaining their essential vinyl character.

Ten years ago, who would have figured that almost every major new music release would also get issued on vinyl? Every day more and more people are learning to appreciate the appeal of vinyl records, but sadly the lack of portability means that for most of us it’s a stay-at-home listening experience. That can be frustrating in a world where we’ve become so accustomed to digesting our music on the go, so lots of new vinyl records come bundled with a lossy-compressed Digital Copy as a free download. Of course, at that point you’re no longer getting the vinyl experience at all, so really, what’s the point? But, what if you could capture some of that analog goodness in a portable hi-res audio version that you can take with you, instead of those crappy MP3 files we’ve endured for so long? That’s the idea behind the DS-DAC-10R, a handy little box developed by the pro-audio mavens at Korg and distributed by Essence.

THE VERDICT
The Moon by Simaudio Neo 230HAD is a state-of-the-art headphone amplifier/DAC that has a healthy, and sometimes transformative, effect on whatever headphones you plug into it.

Like the rest of us, headphones have dreams and aspirations. They know they have to start out small with whatever phone, computer, or AVR comes to hand. But they dream of something better—of an amp and DAC tailored just for their needs. In short, they long for their dream home. If you’ve invested in a good pair of headphones, wouldn’t it be cruel to make your cans sleep on a sofabed in a basement when they deserve more headroom, more purity, the freedom to be the best they can be? The Moon by Simaudio Neo 230HAD just might be the dream home they’re hoping for.

THE VERDICT
About the size of a thick paperback, the Arcam irDAC is a USB DAC that will make your audio files—from lossless to lossy—sound great.

The USB DAC is the missing piece in many of today’s audio systems. Most AV receivers have iOS-friendly USB inputs, but few have the PC-friendly kind. If you want to connect a computer’s USB output to your system, you probably need something like the Arcam irDAC to mediate between computer and system.

THE VERDICT
Though not ideal for more demanding headphones with challenging music, this is a highly affordable way to improve computer audio.

Bits are helpless prisoners trapped on the hard drive of your computer. If you plug your headphones (or desktop audio system) into the computer’s analog output, you can faintly hear their cries for help, but not the true timbre of their colorful voices. It takes a USB DAC (digital-to-analog convertor) to truly liberate them. And the good news is that USB DACs—especially those suitable for headphones—have gotten so small and unintrusive that you hardly notice their presence. A product like Cambridge Audio’s DacMagic XS is no bigger than a USB thumb drive. But the difference it can make to your computer audio listening life is very big indeed.
