And to start something else, I replaced the Wireworld Electra power cord on my preamp with first a Shunyata Venom 3s and now a 1m Transparent Audio High Performance Power Cord, the second from the bottom of their line. What a difference! The bass is more extended, and with some additional detail. That was a pleasant surprise. I got the HPPC out of curiosity, but didn't expect the improvement I heard. The Shunyata Venom 3s cord also gripped better than the WW, but the low frequencies weren't as strong. The HPPC fixed that.
I'm no longer a semi-skeptic on these things. In some cases even the power cord can change the sound of a system/component.
