Cheers for the info....

It looks like the Onkyo and Imerge units are identical apart from the Onkyo swaps the optical digital output for a tv-output. I wonder if the Imerge would work with the Onkyo net-tune software?

Also - I wonder how the architecture on these units compares to the rio. e.g. in theory would they play back flac and/ogg files given the right software....?
