I've owned the Frey and Au in different systems so it is difficult to give you the AB comparisons you are looking for. I can say that my complete E series, when completed, sounded amazing with Reynaud Emeraudes and whatever tubes they were hooked to. The best synergy came when all IC's PC's and speaker cables were AU.
I later decided to go with a Vandersteen Model 5 and ended up selling off most of the Au cables, speaker cables being the main reason, and I now have Frey interconnects. Only trouble is I bought Anticables for the speakers just to get started and they are the weak link. I'm tempted to go with either Frey or Au for the speaker cables but the Vandersteen speakers have a lame 1976 spade termination that requires a 1/4 inch spade that no person will ever want to buy even at 1/2 retail.
I don't mean to ramble but just want to give you an idea of where I am at. If I were you I would first try the Au since you already have the speaker cables. Add some "E" PC's over time and you will most likely be happy.
FWIW the Nordost line sometimes gets a bad rap of being bright. I think if the power source is well addressed, and the components are neutral, Nordost cables can really add a dimension and refinement that is not easy to come by with any cable regardless of price or position in the lineup. Also delicacy and air can easily translate to bright if a system is lean to begin with.
