Your amp, Musical Fidelity 550k - Monoblock, is a poor match for B&W 802D - sound will be bright and you will experience something that Missioncoonery described.
I am exptemely happy with my B&W802D but it took me literally years to find right amplifier (Spectron) for me.
I don;t know C4,sorry - according to the posts above should work fine for you.
