Why would I need a network streamer?

I was going to buy MXN10 but, after some deliberation, I couldn't get my head around why would I need one? Please help (not an audiophile here, nor a very heavy music listener)

My current set up: Denon AV receiver with 5.1 speaker setup.
My music source: Tidal. Denon already supports Tidal Connect natively and also via HEOS app.

What advantage would MXN10 give me?

Please convince me to buy/not buy one.
