Has anyone used any of these paired to an iPad or similar to get their high res audio into a processor? I'm finding quite a few newer models that Support over 16/48 and will pair with any device. Outputs optical or s/pdif coax. Some also have built in dacs for outputting analog. I'm wondering what the quality really is. I'll probably order a couple different ones over the next couple of weeks to pair up with my iPad, streaming 24/96 , then into a desktop dac that has a display that reads what is being fed into it.
