I am sure it is already on the list, but I just wanted to add my public support for adding the Expanse headphone cross feed to the rest of the dCS range, well, specifically the Network Bridge, as that is what I own! . It seems like it would be a great addition for my Stax set up.
Having read the white paper, I get the impression it is all digital, but if it is also accounting for the amplifier stage in some way, that would be interesting to know.
