I too use a remote app on my iPad, to control whatever is playing on my iMac in the other room. This has resulted in the SACD player gathering dust, especially since more and more titles are available in high-rez on HD Tracks. The iMac is connected to my Bottlehead gear via an HRT Music Streamer II through a very long, powered USB cable. I had a Squeezebox Touch for a while and it did the same thing, but I didn't care for the analog outs on the Touch when compared to the HRT (let alone, a proper DAC). While my iPhone also has the same app, it's harder to see on that tiny screen!
