I tried the Pass XA100.5 on my C4 mkII, didn't like them.  Currently, I have the Ayon Tritton III and Musical Fidelity Nu-vista for the C4. I switch back and forth between the 2 amps, depending on my mood.  Ayon has more sparkles while MF Nuvista is smoother and has more bass.
I've been using the combo : McIntosh MA8000 + Dynaudio Contour K5.4 for nearly two years, and it sounds great.
