I own the dcs combo too and you can believe me that this combo is NOT very sensitive to transports.
Reason is a superior jitter processor.I tried several transports,all of them were ok.
What I want say is, when you go for the ultimate and you can afford it, ok, but the difference in sonics is not so huge you will expect.
I think the Wadia 3200 is a really good unit. Cheap 2 . hand and most people have no idea, what they sell....
When you want to go up, there is imho no danger with Wadia.
