Headphone Amp/DAC Reviews

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.

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.

There is a way to make your music sound better. Well, OK, there are LOTS of ways to make your music sound better. If you're looking to improve your digital music, beyond new speakers, amps, and so on is a bit of technological wonder called the DAC, or Digital/Analog Converter. This is what turns your music files into something analog you can actually hear.

Receivers these days tend to have built in DACs, but just because they're there doesn't necessarily mean they're any good. A great sounding DAC can smooth out your digital audio, making it sound more natural and realistic.

Firestone Audio's tiny ILTW packs a lot into a tiny frame, for not a lot of money.

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.

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.
