Electrolytic + film bypass

I use a 100AH SLA battery with low 2 milliohm internal resistance to power a CDP that draws less than 1A. There was audible improvement after adding a large electrolytic cap array between the battery terminals, futher improvement after adding a second smaller electrolytic array inside the CDP, and improvement once more after placing .1uf teflon and .47uf film bypass caps at the chipsets. Film bypass caps by themselves are not enough with batteries. There seems to be no diminishing return on capacitance, even with a large battery powering a light load.
