OP the computer will just be for an app that is the User Interface. Personally, I like a tablet- ipad if you are an apple fan. you just view information and select your music on it. The streaming bits with the music content go directly from the Internet into the Bricasti.
unfortunately, there's no guarantee that their ethernet is the "best" input. seems like it should be, but my PS Audio has a network bridge, and as others have mentioned, it's inferior sounding and aggravatingly unreliable. So, I have a nice DAC, but it requires a PC or streamer.
I am not yet convinced that a PC with an i7 and 8GB of RAM with SSD and only running the OS* plus the streaming app is so awful as many make it out to be. but also have not had the $$ to try a $2K + streamer. I need to find someone local to either let me borrow that superior streamer, or to let me try my DAC in their system= Rogue Cronus magnum III and ML ESL-X ,DH lab USB cable should be sufficiently resolving.
* I acknowledge, that windows is running way too much in the background, but there is so much more power in this system than you'll find in any streamer. I know there is zero contention for compute resources!
