Thanks to everyone for the input. The Innuos Zenith MK3 really rises to the top.
For those who think a ripper is unnecessary I think that means I would either need a NAS or built in storage in the streamer. Could I not just continue to access my current ripped CDs in my Mac Mini via the Streamer (essentially making the Mac Mini the NAS)? If yes, would the Pulse series be a better option than the Zen series? I kind of like the idea of the simplicity of an all-in-one device but I agree that ripping CDs is rare.
As for USB cables, would a Belkin cable be fine?
