OLESCHOOL, I would keep the Bel Canto DAC and add a streamer that has no dac, of course connection will be key. Does the Bel Canto have a USB AUDIO 2.0 Input? Its not mandatory, you can use RCA digital as well. The Aurender X100L ($2500 range) is one of the finest sources for digital streaming, not only for its awesome sound but ease of use as well, with the Conductor app for your i pad :-) ALSO, the N100 series of streamers are excellent as well with less storage and the same great Conductor app. If your DAC is to old and does not have the USB audio inputs I would suggest getting rid of it and if you dont want to spend $8000 on a Aurender complete DAC/streamer then I would highly recommend the Bluesound Node 2 $500.
