digital interfaces tend to produce jitter - this is a fact. That said - a good DAC can completely compensate if it uses asynchronous re-clocking or other clever techniques to reject the inevitable interface jitter. Depending on the Wadia's DAC;s jitter rejection capability you might be better off with a Wadia player (assuming the Wadia has very little transport induced jitter which it should) but I'd humbly suggest it's almost impossible to make a call without trying it in your specific setup (to many variables)
