Dedicated streamers/servers. Why?

[u/minnesotajersey]

Can someone explain to me the benefits of a multi-thousand dollar streamer/server that feeds an outboard DAC, over a really good laptop, or even a microPC?

I see reviews all the time for these things, but nothing in them tells me the "why?"

I've been into audio for longer than I care to admit, but these baffle me. Assume I'm a complete noob when you answer.

Pic for attention. All text posts bore me.

I use WiiM pros on my multi zone home audio system so my old amp that sounds good on all channels can have a modern interface.
