Actually, I think you'd likely get a more noticeable kick if you switched out that silver interconnect for some Cardas Cross. I used to have Audioquest silver interconnect (Cheetah?), and the switch to the Cardas was like going from a cold shower to a warm bath. Silver does interesting things to the highs, but the balance with the lower mids and bass has always sounded odd to me, and, in the end, unsatisfactory. I finally swore off the stuff.
The Cardas Cross power cord will sound a bit warmer and fuller-bodied than your standard power cord. But I have to be honest and say that, in AB testing of power cords, sometimes I've heard more difference than others, and I could probably be fooled in a blind test.
