I hear a slight but distinct capacitance effect with my Koetsu and an SUT. I have a 250-450pF variable cap across the SUT outputs. All my records sound good somewhere within that range.
As I said, the effect is slight, much less than resistive loading; indeed, you may not even hear it until you assume the listening position.
Unless you are dissatisfied with the sound at 0, I would leave it there, because all caps (except air gap) introduce distortion. If you are dissatisfied, buy pairs of styrene caps (MIT is very good) of 100, 200, 400, 800 pF. Don't forget to evaluate from the listening position only.
