interconnect help

[sonicpower]

i am currently in the process of putting together a klipsch/denon audio system.i had purchased a mcintosh rca interconnect for multiplayer to receiver.i have given it plenty of burn-in time and tweaked the inputs to a very satisfiable reproduction(to my ear).my problem is i feel there is more i can do to tighten the bass and warm the highs.i am thinking the kimber kable hero interconnects or possibly the analysis oval+ interconnect may help.i have read from others the klipsch klf are inherantly bright and these two cables will relieve some of that.are there any klipsch/denon people here can help steer me in the direction?thanks for any help.
