Streaming

JW, bluetooth is a way to transmit digital signals. It is low fidelity but fine in a car.  WiFi is the "network" environment to enable transmission of digital signals either with or without an ethernet cable. My set up.....modem receives wifi signal from my service provider via coaxial cable. Modem is physically linked to the router with an ethernet cable, which distributes the signal creating transmission of your "wifi" network. Everything runs off the network. I have a one box streamer with a dac that is ethernet cable connected to my router. The streamer-dac is connected to my integrated amp with analogue cables. I use a music streaming service Qobuz that I access through my Ipad or iPhone with an app....it's fairly simple and you don't need to be a computer expert. I've been into streaming music since it first was available, years ago.
