Upgrade power cable for Quads???


Hello,
I enjoy a pair of Quad 988 esl's and I was wondering if anyone who owns (or have owned) Quad esl loudspeakers have tried replacing the factory power cable with an after market 'high end' power cable. And if so, did you notice any sonic improvements?
Thanks

For my system, it is not a subtle improvement.

I get fuller over all sound with the Soundstring PC, which results in much more bass. Now I am seriously contemplating bass traps for my room. If I were to quantify the differences in "bass response" I give stock cables 4, Signal Cables 6, and Soundstring 8 (scale of 1 to 10).

My friend's opinion was that somehow I was not getting enough power to my Quads before, and that now I am experiencing the full potential of the Quads. I am not sure if PC's actually "color the sound" e.g. add more bass, or have characteristics.

I do believe that everyone's experience will be different, and it will vary depending on the system. Since I am still burning in my CT6 preamp, and the cardas golden cross IC between the preamp and MV60 amp, I plan to wait awhile before making any decisions on the PC.
No question that everyone's experience will be different and everyone hears differently. Stik checking your system page I think you would probably benefit from some room treatments. Base traps in the room corners and in addition treatment of the walls behind the Quads has helped my setup considerably. Hope you’re enjoying your new CJ stuff!
i have quad esls and i owned quad 63s. i notice changes in presentation associated with changes in power cords.

i cannot recommend a particular product, as there are too many variables.
