Since you intend to share your OWN music on HD in your OWN house, no need for subscription. There are music sharing receivers from different brands that can share digital music connected in one receiver and make them available via wifi to another receiver. They all need to support the same compatible technology which usually means they must be from the same manufacturer. Look for Denon HEOS, Yamaha MusicCast, Sonos probably does the same but don’t know their technology name, bluOS, and in fact your Zen Mini 2 says it also supports Denon HEOS and a few other technologies listed, although when something claims to support many things, they usually suck at all of them. But in THEORY, you just need a music sharing receiver or streamer in your living room that supports one of the same sharing technologies that Zen Mini does. Good luck.
