The input impedance of the poweramp...

...is parallel with the (output) load resistor of the preamp, and that paralleled impedance determines the filterpoint of the output cap. The lower that resistance, the HIGHER the filter point. That's one reason others are suggesting you increase the size of your preamp's output caps. The higher value the output cap, the lower the filter point.
