Somewhat strangely, neither of them come with a remote.

The back of each device features two RCA ports (one for line in, one for line out), a coaxial input and output, digital Optical in and out, and an Ethernet port for wired internet (both models also feature built-in Wi-Fi). The Echo Link is about half the size of the Echo Link Amp, due to the fact that it doesnвЂ™t actually power speakers on its own (more on that below), but even the larger Amp is about the size of a lunchbox, and thus very manageable to place in your home. Both feature large volume knobs on the front and nothing else, and even the LEDs that illuminate when you adjust the volume quickly disappear after you turn the dials, making these devices extremely unassuming and minimalist.

Two devices, one designД«oth the Echo Link and Echo Link Amp are simple black boxes that could easily disappear inside your existing home theater or audio setups. These devices arenвЂ™t cheap, and theyвЂ™re also quite niche - but they do deliver on their promise to transform any вЂњdumbвЂќ hi-fi system into a smart, sweet-sounding listening hub. Fitbit Versa 3ДЇirst revealed at AmazonвЂ™s mega hardware event last November, the $200 Echo Link and $300 Echo Link Amp aim to bridge that divide, offering something for those in search of premium sound and the simple voice control of Alexa for their high-end audio systems.
