From your two options, I would probably go with the Kimber with Wattgate connectors for a digital source. The Triode Digital American model uses un-plated copper IEC/plug and these are not very high resolution. The brass elements in the Wattgate connectors work better for the "constant voltage" needed in digital sources. I have had a lot of success in using the brass Wattgate connectors in digital sources, but I would not necessarily use Wattgate for a preamp/amplifier.
Wattgate brass conductors push hard on the voltage and are good for digital. A Rhodium plated connector would be an upgrade and give you even more high frequency "openness". In my opinion.
