+1 for @dwest1023 's Idea for starting with a laptop. You are familiar with the interface and you can get a good idea of how things work before you drop a bunch of money. I'm using my ASUS ROG laptop for streaming and I've compared the sound of Qobuz to my CD rig (being careful to play the same version) and they sound identical to my ears.
One tip I will give you is that streamers come with their own software and each interface and functionality can be quite different. I would suggest that you pay a lot of attention to the streamer's interface before you choose which one you buy if you go that direction.
If you like the idea of having a huge database of information at your fingertips about the music you are playing you may like Roon. You can use Roon on your laptop so you don't need a special streamer to use it but you will need a DAC with a USB input. But I recommend starting simple and working your way up from there.
