Have you considered the $550 NAD Node 2i? Works with or without a computer (wired or wirelessly, Windows or Mac), analog input, Airplay, with any coax/optical input, and can stream internet radio. Outputs to headphones, 2-way Bluetooth, an amp or powered/active speakers plus a powered subwoofer. Can also be controlled via a smart phone, tablets, or Amazon Echo/Alexa, Apple Siri, or Google Assistant (voice recognition). Runs off built-in very stable BlueSound operating system (fully MQA compatible) with access to many streaming services so no extra software needed. Plays S/PDIF up to 32/192. Excellent sound quality for this price has trickled down from the NAD Master Series (I own the M10 "streaming amplifier).
