Just a guess,but From what I can see the Nordost cables could certainly be thinning out your sound..Great cables but the ( Red Dawn ) Nordost can be brutal if not used in the right application...I would suggest finding a Virtual Dynamics " Nite " interconnect to throw in the mix..This will give you much more Full Bodied sound ( and great bass ) and should help considerably..I would try only 1 pair of interconnect cable and add more if needed..
Thew other option is to lose the Kefs and go to a warmer speaker......Good Luck
