Following up on some earlier recommendations for the Wireworld Silver Electra 7 power cord, I've currently got on loan a one meter length of this cord to try out with the DAVE (they didn't have the one and a half meter I asked for, and I now think I probably need two meters). It was new out of its case but I've managed to give it about 50 hours run-in. Straight out of the case, my first impression listening with the HE1000 v.1 (Silver Dragon) and the Utopia was that the sound was more detailed, cleaner and much much brighter (far too bright). The Silver Dragon on my HE1000 and using the LPS-1 powered microRendu already hinted at a little brightness in my system but the Silver Electra took it right over the edge. Fifty hours in and some of that brightness has gone but some still remains. I wonder, could I expect to hear much difference with a longer length of cord and/or with a Furutech plug (the cord I have has a standard UK 3-pin plug)? Thanks.
Sadly, the Silver Electra 7 is not working out in my system and will have to go back. I've given it over 150 hours run-in and while there is much to like about it with the DAVE - greater distortion-free clarity, transparency, separation etc - the problem is that it accentuates the slight brightness of the microRendu, and there are too many instances when this detracts from my enjoyment of the music. I should say that I have been doing most of my listening with the Focal Utopia, which with stock cable is not very forgiving of this kind of thing (less so than my HE1000). It's a shame as I think the Silver Electra is reasonably priced and in addition to its audio strengths it does wonders for the picture on my plasma tv.
