Amazon’s Echo Link Offers Hi-Fi Streaming at a Competitive Price

It’s easy to see why Amazon’s Echo Plus and Echo Dot devices have proven to be so popular: they offer a convenient and inexpensive way to bring Alexa into your home. Music streaming is certainly one of the primary reasons to buy into the Echo hype.

For quite some time, however, the Echo family has had a problem. While many people would be sufficiently satisfied to slap an Echo Dot in the corner of their living room, audiophiles weren’t so convinced. After all, why purchase an Echo Plus or Echo Dot when your home is already filled with a much higher end stereo system?

How Does Amazon Echo Link Work

That’s not to say audiophiles are stuck in the past. The benefits of streaming from vast libraries of music are obvious, but quality still matters. And for that matter, you don’t even need to be an audiophile per se to want to keep your existing stereo system intact.

For years, consumers have turned to solutions like the Sonos Bridge to add streaming functionality to their existing hi-fi systems – lossless or otherwise. Amazon, as they are wont to do, have capitalized on this market by offering the Echo Link, and at roughly half the cost of the Sonos Bridge and other competitors.

What is the Echo Link?

In short, the Echo Link is a simple piece of hardware that sits between your amplifier and other audio components (turntable, Bluetooth, etc.). The Link then pairs with other Echo devices on your network to treat your existing stereo setup as one big Echo device. We’re talking analog in/out and hi-res audio support in addition to everything else your Echo Dot or Echo Plus may support. If you were disappointed with your attempts to plug an older Echo device directly into your stereo system, then the Echo Link is for you.

Note that the Echo Link is not an amplifier itself. If you are just building your hi-fi system, then the Echo Link Amp offers everything the Echo Link does, but with a high quality built-in amplifier.

Deciding Factors

While the Echo Link is a strong competitor on price alone, for some audiophile consumers, there are still considerations to be made. Most importantly, perhaps, is that the savings may not be enough to jump ship from existing systems like Sonos. Additionally, while the Echo Link provides a satisfactory solution for your existing stereo system, it does not allow streaming to other Echo devices.

Regardless, the Echo Link is a great solution for those who likely spent hundreds filling out the stereo cabinet with great gear in a prior era. The Link may be just what you need to pump new life through those speakers!
