Power Cables and Power Conditioner

I bought my first PS Audio (PSA) outlet as well as a PSA power cable.  I had intended to use the power cable to go from the new wall outlet to the conditioner but when I got home I realized the Furman ELITE-15 DMi has a fixed power cable.  I thought dang it and was going to return the PSA cable but then decided to give it a try.  So I ran the PSA cable from the Furman to my Rogue Audio Preamp.  I swear I think there was a moderate improvement to the overall image.  But of course this could be placebo and I have not done a bunch of with/without listening but am happy so far.


I assume the Furman filter is doing its job and adding the PSA power cord to the Pre is preserving this current as best it can. I would like to add another cord for the DAC and the power amp. But thought I would float this probe to see what other people do in similar situations as this.
