Headphone Amp/DAC Reviews

Parasound has packed a few more features into their Zphono moving coil/moving magnet pre, adding to the Zphono·USB ($350) an A-D converter and (obviously) a USB port, making it even more handy as a general-purpose interface for those with older and esoteric turntables (or pretty much any other stereo gear) looking to digitize their collections.

THE VERDICT
Pro-Ject’s compact amp/DAC pairs especially well with modestly priced headphones, and it can also serve as a stereo preamp.

More people are listening to more diverse high-resolution audio formats through higher-quality headphones than ever before. But ideas about how to feed those headphones vary. The headphone amplifier/digital-to-analog converter, a popular hybrid product, is among the most tireless shape-shifters on the audio scene. I’ve reviewed Amp/DACs as compact as a USB stick and as big as a full-size rack component. At about 4 x 1.5 x 4 inches (WxHxD), Pro-Ject’s Pre Box S2 Digital falls somewhere in between. You wouldn’t carry it in a pocket, but it doesn’t take up much space on a busy desk.

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.

OK...I'll get this out of the way upfront. Despite the great reviews it's received, before I'd actually encountered it in person I was suspicious of the rCube. Arcam's a company I know and trust, they build a fantasic line of products (including some impressive all-in-one systems), and they know their wireless and DAC design.

When Audioquest released its DragonFly USB Digital-Audio Converter back in 2012, the tiny USB-stick DAC quickly found a niche with audiophiles seeking to improve the sound quality of music played on their laptop computers and listened to via headphones or desktop speakers.

We've long been fans of CEntrance's portable USB DAC/headphone amp, the DACport; in an expanding market of bus-powered USB DACs, the venerable unit (along with its streamlined sibling, the DACport LX) remains a favorite of, and reference for, many reviewers of portable audio gear. Now they've gone ahead and put out a complete two channel system, of all things - the Audiophile Desktop System.

Housed in a billet-like slab of aluminum, the HRT microStreamer’s clean, utilitarian design tips you off right away that it means business. In this case, that biz is performing the same basic tasks as the Dragonfly, including decoding files with up to 96 kHz/24-bit resolution. And at a mere 2.5 inches, it checks in for work in a similarly compact form factor.
