If you are happy with CD resolution you might consider a Sonos system. I use a paired network hard drive to store files and can play them using my computer, iphone or iPad wirelessly to either Sonos speakers, or using a Connect unit to input the wireless signal to a system with a separate DA converter (the on board DA conversion is OK, but your Gugnir is better).
At this point, Sonos will not stream any higher resolution than CD - I use dBpowramp software as a ripper and it includes a utility to downsample and save as new playable files, anything you have at higher resolution.
