Agree with the Nordost. I've never found a pair that I could tolerate, but for what you are looking for, they may just do the trick.
I've also had a pair of AudioQuest Dragon (silver). The most spectacular cable I've owned in many regards, such as explosive bass and tremendous resolution. But, I always felt I was sitting in a dentist chair, and was deriving the opposite of happiness when I listened to my system. Chasing the problem all over the place, one day, I switched my former copper loudspeaker cables back into the system, and instantly had music again. Rare and pricey, but if you run across them, you may want to give them a shot.
