I am sorry if this seems like a Noob question, but it is something I have been thinking about when considering purchasing a Direct Stream Junior to go along with my M700 amplifiers.
Currently I use a custom built music server that is direct connected to my DAC using USB. I run Roon Core and HQ Player on the server which is an i7 CPU, Gold Power Supply, 16 GB RAM, 2 TB of SSD drives, etc. The server is running Windows 10 professional. I keep all of my music on the server (backed up on the network of course, on a couple of different drives actually). The server has built in WiFi which I use to connect it to the network, with an external WiFi antenna that is mounted on my rack. I use the WiFi to do remote desktop for occasional maintenance on the machine, to copy new files to the machine, to adjust settings in HQ Player, and for the Roon controller devices to connect to the Core. I do not stream from my NAS or online, Tidal, etc.
The machine also has two high quality Ethernet ports which are not currently being used because there is no wired Cat 5/6 in the vicinity of the audio system.
My question is this, if I add a DSJ will I still use only the USB input or would I be able to run an Ethernet from the Music Server direct to the Network Bridge? If this can be done is there an advantage of doing this versus simply using USB?
Is there any other primary purpose of the Network Bridge other than streaming from a NAS or online (I have no interest in MQA, etc.)? Can I use it directly from my Music Server machine?
