THE VERDICT
The D 3045 is a surprisingly powerful compact integrated amplifier with an eminently capable onboard DAC that's equally at home on the desktop or component rack.

Five years ago, when I examined NAD's $399 D 3020, the progenitor of the D 3045 before us here, I liked it—a lot. The D 3020 was among the first of what I've come to call DAC-lifiers: small-ish integrated amps with onboard digital-to-analog facilities intended for audio-streaming or computer sources and projecting at least some level of audiophile sophistication.

THE VERDICT
Cambridge Audio’s commemorative Edge A combines top-shelf sound with gorgeous industrial design. The price may be a cut above average, but the Edge A is no average integrated amp.

Do you really need a $5,000, 54-pound, two-channel integrated amplifier? Yes, of course you do. Especially if that integrated amplifier is the new Edge A from Cambridge Audio, a British firm with a long record of seriousness about sound reproduction. Cambridge’s gear has always struck me as a rigorously high-end/high-value proposition, but the Edge A looks, tastes, and smells more like a no-holds- barred statement design, the kind we’re more likely to expect from a company whose bottom line is that they don’t give a fig for the bottom line.

THE VERDICT
Yamaha’s unique DSP-surround technology sets apart what is otherwise still a strong A/V receiver in a highly competitive market niche.

I get to review a lot of A/V receivers. Familiarity breeding— well, familiarity— I confess that I tend to sort new examples into one of three classes. The flagship models cost a lot, pump out 140 or so watts from each of at least nine and often more channels, and they tend to cram in every conceivable feature. Entry-level jobs are cheap, five- or seven-channel affairs that usually top out at 65-or-so real watts per channel and incorporate more basic feature sets.

THE VERDICT
An excellent solution, for those who can afford it, for a streaming/computer-audio system where sound quality is as important as features or user interface.

Is it an integrated amplifier with onboard wireless and network streaming, or an audio streamer with built-in amplification?

Yes. The Uniti Atom, from British iconoclast Naim Audio, is both of these, as well as a quarterback for the company’s Mu-so wireless- multiroom ecosystem (and a few other things mixed in). Like all Naim products since the brand’s inception in the mid-1970s, the Atom is distinctly different from most competing designs in both appearance and operation; the company’s proximity to the powerful vibrations of Stonehenge doubtless has something to do with this tradition. That said, the Atom is less different from its competition than many a previous design, because this sort of streaming amp is what the classic stereo integrated amp seems to have morphed into, here in the post- physical-media 21st century. But perhaps the rest of the world has simply caught up, or caught sideways, to Naim.
