Back to Dynamics20 for a moment. I would expect the combo of Wadia 850 and Plinius SA100 to be a bit sterile and analytical. I doubt that PCs will fix this. I would experiment with perhaps a Cardas Golden Cross interconnect which will definitely change the sound compared with your Diamonds.
Neubilder, I felt exactly the same as you until my curiosity caused me give it a try and to dismiss this PC snake-oil altogether. I tried a high-end PC and didn't like it much, but the sound was, to my utter surprise, different. My next step was to make several PCs using different cables and they all sounded different. I was very perplexed and could not understand what was happening. Even small changes like to the outer insulation made significant differences. I finally gave in and tried the seemingly exhorbitantly priced ones from the US and actually found one I liked, and bought one for each component. From my playing around and looking at the construction of the cables that sounded good, all I can say is recycled copper sounds awfully grainy, twisting of conductors for common mode rejection makes a beneficial difference, thickness of conductors makes a difference, shielding makes a beneficial difference and the dialectric used makes a significant difference. I don't know why. I theorise that a good PC has a similar effect as a power conditioner, but without the latter's deleterious impact on dynamics, only because that is what it sounds like to me. If indeed a PC had a conditioning effect then this might explain why a few feet just before the component can have an effect when there are tens of meters of basic stuff in the walls and in the lead-in to the house.
