Amazon has announced the Echo Link and Echo Link Amp for audiophiles who want to add Alexa music streaming to their high-end audio equipment. The Echo Link provides multiple audio in and out connections, including coaxial, RCA, and optical. It also has a subwoofer out connection and an Ethernet port for its connectivity. On the front is a headphone out jack and a large volume dial. The Echo Link Amp features the same ports but adds a pair of left and right speaker connections that are used with the built-in 60W two-channel amplifier. The Echo Link will be $199.99 when it’s released and the Echo Link Amp will be $299.99. Neither one is available to pre-order yet, but you can sign up to be notified when they’re available.
