THE VERDICT
The Amazon Echo Link Amp offers an easy way to connect music streaming services to your existing stereo speakers.

With the new Amazon Echo Link Amp ($299), Amazon is sending Alexa off into unchartered territory. The goal: get music out of the phone and into the home, where it can be shared with family and friends. Such a warm, fuzzy idea! Good thing the Link Amp's sound is crisp, clear, and not fuzzy at all.

I'm constantly amazed by the steadily improving sound of real-world-priced components, but it's fun to see how far mind-bogglingly fantastic high-end electronics have come. Yes, I have to admit that there's a certain amount of poseur gear that sports nosebleed pricing but doesn't really deliver sound that's much better than everyday good stuff. Have no such worries here, though. Anthem's Statement D2 surround processor and P5 amplifier are the real deal. Even by high-end standards, their capabilities are inspired.

The Stage One is Aragon's second-generation surround processor, replacing and retiring the original Stage. The Stage One combines a strikingly machined front panel with the latest thinking in surround processing, including no processing at all for us vinyl buffs. And in a concession to those who think there might still be something on the public airwaves worth listening to in this ClearChannel world, the Stage One also throws in an AM/FM tuner. Visually, the robust 5-channel Aragon 3005 and 2-channel 3002 amps share the Mondial-inspired "M" design with the Stage One.

Though it's a relatively small company, UK-based Arcam has long been known to place heavy emphasis on R&D. When I visited the factory a few years ago, I was shown some of the impressive development work then in progress. This effort, said by Arcam to run well over $1 million, has resulted in some impressive new products, including the FMJ AV8 preamplifier-processor and its companion FMJ P7 power amp.

THE VERDICT
The days of looking down on Class D amps are over.

Two and a half years ago, I reviewed my first ATI amplifier, and to say I was impressed would be an understatement. The ATI Signature AT6005 five-channel amp set a new benchmark for its designer, Morris Kessler—to the point where he put his John Hancock on the faceplate.

Last year, S&V editor-at-large Bob Ankosko sat down with Kessler to talk about his design philosophy over the years, and the subject of Class D amps was broached. Kessler mentioned that his current designs were all Class A/B, but he was following the developments of Class D very closely—though the initial efforts in this area didn’t meet his high standards because frequency response varied greatly as the impedance of the speaker changed. He hinted at the time that he may have finally found a Class D solution that he could deem acceptable, which turned out to be the latest Hypex Ncore modules.
