Wow, you have a lot of questions, but that's what the forum is for...
If I were you, I would look at Bluesound. The Node is a very good buy for the money, and its' internal DAC-though not great- is pretty good.
Bluesound has access to quite a number of streaming services (even Amazon).
Given your desire/budget, I wouldn't concern myself with cables.
If and when you are ready to move up the ladder, I would look for either a separate DAC for the Bluesound, or perhaps move to an Aurender (though Aurender doesn't offer the wide range of streaming services like Bluesound).
As far as inexpensive DAC's, I use the Ayre Codex. Though the Schiit Gungnir and Yggy are close competitors and similarly priced.
