Default RC Damper - Parallel C?

What effect do parallel caps have on a RC damper?

I have an amp with an output RC damper of 68R + (50nF x 6 = 0.3uF). If the parallel caps act as a 0.3uF cap that would make a corner frequency of 7,806kHz, if they act as a single 50nF cap it would be 46,834kHz.

Why would a designer choose to use 6 separate caps for the RC damper and only a single cap for the LC filter?
