I have D06 and D05u, but never had the chance to hear the D08. I know, not much help, and not an answer. But, I love both of my players, each in a different system, and they are magical. I think, anyway.
Check out whitecamaross thread in amps/preamps where he sells/replaces a top of the line Esoteric K1 Grandioso with the Luxman D-08u and his comments on why he did what he did (you will have scroll to find the post, there are 1000s of posts in the thread). That should give you all you need.
