Due to the strength and weakness of Nordost, any Furutech end couldn't be a good match for them. Since they'll be too expose and a bit forward, also lack of body and deep bass.
I'd recommend Oyaide F1/M1 which gave me many perfect combination for the cable with similar characteristic to Valhalla. Or the new Wattgate Evolution gold can be your alternative choice (a bit better than old classic Wattgate Gold).
