I use Valhalla IC's, PC's and spkr cables throughout my system, but not exclusively because they can get to be too much of a god thing. But if you find the cost of Valhallas too dear, try looking for used Valkyrje's. For some reason, Nordost discontinued them but they offer 85-90% of Valhallas at much reduced cost. I use a pair in my BR system and they are very fine.
