As slow as USB 2.0 IS you can stream 8 hrs of HD music in about 23, seconds per theoretical numbers 

Hi James,
For stremaing purposes I am symply using a small fanless computer (Zotac ZBox - https://www.zotac.com/us/product/mini_pcs/overview ) which is hooked on my high-end preamp/dac and further amplified by power amp. I only have minimum software installed on it (windows, DAC drivers, tidal and netflix). 

With this setup I can stream all online content (including master quality and 360 Tidal content) as well as all ripped CD's stored on my local NAS. Not to mention that TV set serves as a high-res big screen monitor.

The whole setup works perfectly fine and I see no reason to spent thousands of bucks on fancy streamers, provided of course, that you have a very good DAC/ pream down the stream. The only possible upgrade I would see is perhaps better power supply.

I have the LUMIN A1 which has an external power supply. It’s extremely quiet and has a very dynamic sound. The chassis is solid billet aluminum and gas pretty substantial weight to it. The app interface is pretty good and there’s occasional updates that automatically come via the network. I think the built in DAC is very good although you said you would prefer an outboard a DAC so you could get Lumins streamer only and use your DAC and I’m sure it will sound great.  I think it sounds as good as my analog setup but it is different sounding.
