Apart from converting the TOS inputs I don't believe the 562v modifies the digital signal in any way. I do remember a recent thread where the suggestion was that the 562v did back to back conversion of analogue inputs (ie A-D -> D-a), whereas the 562v2/v3 did propper pass through - I think.
Dare I say it, but perhaps you should have gone for the 518 which would also have cleaned up any jitter. I know you require 2x TOS inputs, but it might have been an idea to upgrade one of those source at the same time.
Try some descent interconnect first, though, and do let us know how you get on.
