Hi. Not sure if this is in right forum but if not will admin move it to where it should be please. My system is old but suits-me Naim Olives to which I’ve recently added a Cambridge CXN V2 Streamer. I have a library of 3000 albums on a mains powered WD hard drive. I’m very pleased with the sound quality of the streamer and it connects very well to my Wi-fi. But the Stream Magic app is woeful. It loses the streamer and is very difficult to reconnect even after a reinstall. The diy bit comes in because my son has suggested I think about using a Raspberry pi. I guess he’s saying connect my 4tb WD mains powered had to the pi and use upnp software to pass tracks to the streamer (I would want to use my tablet as a Wi-fi remote control). I need a lot of help here please as I’m in my early 70s - how does this all hang together, what hardware do I need and what software is required? All help and recommendations would be ever so gratefully received and appreciated.
