My streamer is my MacBook Pro with roon. My external dac is Schiit bifrost with usb unison. This dac is modular for unplugging and plugging in new boards as the technology changes. No need to buy new or send back for upgrades or software updates. Also like how MacBook is updates constantly. Biggest sound improvement I had with this combo was moving from WiFi to cat6 for connection. This change was a 100% sound stage and bass improvement for quobuz.
