Simplified Node under $200 with digital outs only and no buttons

I have bought into the Bluesound ecosystem with a pair of Node players. I want to add streaming boxes as a source to rooms that already have preamps and speakers. It is hard to stomach $350 a piece for several Node Nanos when companies like WiiM exist. All I want is

• App control of the player (no buttons or interface needed on the player itself)
• Digital outputs (optical and SPIDF would suffice) and no RCA (no DAC necessary)
• No audio inputs of any kind are needed

It would be great if such a player could be offered closer to $100 for those of us that prefer more modular stereos and want a true Bluesound whole-house experience.
