Headphone Amp/DAC Reviews

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.

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.

The Wadia 121 calls itself a decoding computer. While the term DAC (digital-to-analog converter) also fits, Wadia understands that nomenclature is destiny. This product just may be destined to change forever the way you hear high-resolution music files, signaling a new chapter in audio history that no audiophile can afford to ignore.

Between increasing your system’s audio channel count to 9.1 or 11.1 and upgrading to a bigger, brighter, or even higher-resolution 4K video display, there’s no shortage of ways to take your home theater to the next level. And while such improvements can certainly add excitement, the basic home theater experience still pretty much remains the same.

The thing that most home theaters can’t do is put you into the action, literally letting you feel what is happening onscreen. The sliding of gravel under the tires. The rock and sway of a boat. The thud-thud-thud of a jet being riddled with gunfire. Providing that experience is the role that D-Box fills.

Back when A/V was just “A,” Yamaha was among the first to elevate the receiver from dormroom necessity to Serious Audio Component. Brand Y then negotiated the transition to audio-plus-video smoothly, and today remains one of the leading purveyors of the all-in-one home theater centerpiece.

The AudioQuest DragonFly USB digital-to-analog converter ($249) and the B&W Society of Sound music download service ($59/year) arrived in my listening room at about the same time. They were made for each other: B&W’s 24-bit FLAC files gave the DAC a better chance to strut its stuff than any CD-quality or lossy audio file at my disposal. And the USB DAC enabled the high-resolution files to do an end run around the awful soundcard in my PC.
