Compact, portable DACs that plug into a laptop’s USB port, extract up to 24-bit/96kHz digital audio using the jitter-eliminating asynchronous protocol, and provide amplified output for headphones and line-level output for preamps, are common enough these days. But in 2012, when AudioQuest introduced its first DragonFly DAC, the concept turned heads. The most attention-grabbing element was no doubt that the DragonFly was the size and shape of a USB memory stick. That such tiny hardware could make possible the playback of high-resolution audio through headphones -- not to mention a high-end audio system -- seemed nothing short of amazing.

As anyone who has recently visited an Apple Store can tell you, iPhone protection is big business -- a high-quality phone case can easily cost $50 to $70. Another big iPhone-related business is headphones -- something that an iPhone owner checking out the Bose, Beats, or B&W options at that same Apple store can readily confirm. The argument in favor of a good case is easy to make -- fixing a broken iPhone can be startlingly expensive (yet another iPhone-related business). But what good, ultimately, are pricey headphones if the sound delivered by your iPhone’s headphone output is, at best, mediocre?

Quebec’s Simaudio has been designing and manufacturing audio electronics for the past 35 years. The company began with preamplifiers and power amplifiers, and later, following the demands of the market, added CD players and standalone digital-to-analog converters (DACs). More recently, Simaudio has launched a series of components incorporating their Moon intelligent Network Device (MiND) platform, which enables streaming audio from your computer, network-attached storage (NAS) device, or the Internet. It should come as no surprise, then, that Simaudio has brought their electronics-design experience to the thriving market of headphone audio -- with first their flagship 430HA fully balanced headphone amplifier ($3500 USD; add $800 for DAC option), and now the subject of this review, the more modestly priced Moon Neo 230HAD ($1500 including DAC).

I think I like reviewing headphones and mobile audio gear more than I do full-size hi-fi components. The thrill of unboxing a new set of speakers retreats pretty quickly once the outriggers are hooked up, minute adjustments are made to toe-in angles, and the speaker cables are attached. But you live with a pair of headphones. You touch them, grab them, adjust them, and, most important, wear them -- they’re almost as much a fashion accessory as a watch or a pair of eyeglasses. Top-quality appearance and sound are necessary but not sufficient. The quality, durability, and comfort of the materials, the feel of the controls, become much more meaningful when they’re part of a device you physically interact with multiple times a day. A loudspeaker merely shouts at you from a distance.

In a recent column, I complained about the rapid growth in the number of lookalike headphone amps that are little more than a DAC-amp chip stuffed into an extruded-aluminum box. The Aurender Flow ($1295 USD) is the exact opposite: a product that represents a major rethinking of what people -- specifically, audiophiles -- need in a headphone amp.
I’m writing this review on a sleek, highly portable Hewlett-Packard Spectre laptop equipped with a modestly sized solid-state drive (SSD) that makes me wish I’d spent the money on a bigger drive. Despite my efforts to move my storage-intensive audio and video files to an external drive, my SSD has just 2.2 gigabytes of space left. Yet thanks to the Flow, I can now use this overstuffed computer to access my entire collection of digital music files, and I can add more music without worrying I’ll run out of space.

Traditionally, headphone amps have been afterthoughts -- relatively low-cost circuits built into receivers, computers, portable media players, etc. After all, even with relatively insensitive headphones, the amp usually needs to put out no more than 50mW -- 0.05W -- to drive headphones to loud volumes with no audible distortion. But with headphones’ recent surge in popularity, and the concomitant growth in the number of hardcore headphone enthusiasts, many manufacturers have been putting serious design effort and resources into their headphone amps.
