B&W 702S2 jumper cables


I have been using chord shawline X speakercables and they sound great. I wanted to replace the metal jumperplates on the speakers with something better so i went for the Chord Signature Ohmic links. I can clearly hear the difference but the highs are way too much. Too bright and the famous "SSS" is clearly irritating. Am i doing something wrong or do others have similar experience ?

Perhaps the Chord Signature links are revealing the actual treble response of the B&W 702S2 while the standard metal plates toned down the brightness of the tweeter. I have the Chord Signature links and they do not show the character which you have described here. I have them on Harbeth Super HL5 Plus.
I have them for a months now and it got bad when i installed my mcintosh ma7200 about 3 weeks ago. I tried with/without jumpers multiple times. Every time the standard plates win. Its too late to send them back so i made my decision and sell them on ebay. 
Strange but for me no, more jumper cables. 
Maybe they need more time to burn in to settle in as they say. I question the jumpers are adding this or maybe they are passing on something upstream? If they don’t work out, hopefully you can return them. 
Yes, I read this too and tried all configurations. No good result.
They sound the best without jumper cables.
Nordost has a nice diagram on what’s called the diagonal connection which I prefer in my system. Several ways to hook up jumpers so you might have to experiment a little to find what works for you.
