I’m streaming from both Qobuz and Idagio. I receive the signal through an Arcam streamer. My stereo rig consists of separates: Benchmark amp and DAC, CJ preamp. GoldenEar speakers, etc.Your Arcam supports UPnP. Software is available for UPnP streaming from Windows and Mac. Look at JRiver, Plex, Universal Music Server and other software.
What I want to do is download normal and hi res files from different internet sites and stream them wirelessly to my system.
If your computer/laptop is a Mac, you can also use Airplay as you are now doing with iPad.
