C10 looks to be a "bootstrap" so increasing its value will increase (or rather maintain) its effect at lower frequencies. It enables the output to swing that little bit closer to the rails so raising the maximum output voltage swing available. It probably also lowers the absolute distortion figure. The change will only affect the lowest frequencies though.
