Welcome!
Recently picked up a NAD M10 "streaming amplifier" ($2750 MSRP) that is a thoroughly modern all-in-one box. Uses BlueSound, does MQA, streams Tidal, Qobuz, and internet radio. Has analog and the full range of digital inputs including USB flash drive, has preamp outputs, dual subwoofer outputs, and 100 wpc stereo outputs. Is compact, lightweight, efficient, and has a large bright clear touch screen but can also be controlled via Android, iPhone, Windows, and Mac. It's providing the best sound I've ever had. Not recommended if you want to show off your gear or are a constant flipper of gear.
By the way, Roon and BlueSound would be mutually exclusive. BlueSound comes on NAD gear only. And note that the M33, a souped up version of the M10 has just been announced (at twice the price). Less costly options to the M10 are the C658 ($1650 MSRP) and Node 2i ($550 MSRP).
