I'm looking for a digital dock that will work on two of my older receivers. I would like it to have analog options as well. My newer one uses air play so I'm good there. My iPods and iPhones all have Bluetooth. The two older units do have digital TOSLINK or digital coaxial inputs. They don't have USB or HDMI. I have been looking to get something on a budget of less than $200. That rules out the Wadia which is more money and I'm not sure I would notice the sound difference in the Wadia based on my equipment. (Do they still even make an iPod Dock?)I have seen info on the Pure i20. Any other thoughts/ suggestions?
