I just sold a set of Nordost Heimdalls and a set of Blue Heaven IC's. They sounded great in my system, and I was going to upgrade to Tyr, Valhallas, or Odins. Instead, I am waiting on Linn IC's since I've always had good luck with them. I have to use Monster cables while waiting for the Linns to arrive. Guess what...my system still sounds fantastic. I would have kicked myself paying the kind of money to get the Nordosts, however their powercords and QB4 distribution box did make a difference for the better, so I guess it really matters what type of system one has.
