Don’t overspend, especially at first. It’s something you have to use, know, understand, and analog logic doesn’t apply. There are a lot of uber expensive options out there that don’t add SQ and just address the nervosa.
After you know what you’re doing, feel free to pull out the wallet. Don’t start that way.
I’ve built a couple great PC streamers and many swear by their Raspberry Pi’s. But if you’re not interested in learning about PCs, I’d go for something like an IfI Zen or a Pro-Ject to start. Consider using Roon, which is one of the best things about streaming. Streamer has to be compatible.
