You didn’t offer much info. What will you be streaming? Amazon, Tidal, Qobuz or other HD service? Pandora etc? Do you need to stream wirelessly? Bluesound Node 2i does that, but many streamers have to be wired with ethernet (they don’t do bluetooth), so you’d need an ethernet connection to the streamer.
Streaming ripped music stored onboard or on an external HDD/NAS? Do you want to use Roon?
Do you want one with a built-in DAC or do you have a DAC?
How important is the native app (for phone and tablet control? They vary widely. I use the Tidal app (good) on phone, tablet and desktop, or ROON. The native apps from different mfrs get varying reviews (Audender Conductor, which you’re locked in to using with their unit) gets mixed reviews. Innuos is launching their own app which they say will be great (we’ll see). BlueOS gets mixed reviews.
