Of course David is right. The best result is for just the electrolytic alone. The attached shows the comparison. I have chosen the values that Audio Research used in the LS22 - 6,600uF (3 x 2,200 in parallel). The vertical axis is the same in all three cases for direct comparison.
The results look odd, did you include the 0.22uF?
