I will weigh in with my experiences. I am currently auditioning a pair of Nordost Heimdal IC's on my CDP to amp and I am quite impressed. They don't sound anything like the Blue Heaven's that I previously tried which were somewhat thin and whitish sounding. Amazing sustain and air to the upper end, but not very well balanced.
The Heimdall sounds very very good with my Audio Refinement CDP, and I've tried many cables with it (both power and IC). The bass is simply the best I have heard with it. Very deep and clean with excellent heft and purcussive attack. The midrange is really enjoyable too in that I have the feeling of detail, but it seems to push back and smooth over any graininess or edge to voices or brass that I have experienced with some of my recordings. I find I can really crank it up where I could not before on those CD's.
The highs are sweet with good color, though here not quite as open or extended as the Transparent cables I've tried, and not quite as rich in tonal color (Transparent Music Link 100, Plus and Super). But I've found that many CD's that were bright and hard to listen to with the other cables, sounded very accurate with the Heimdalls but quite listenable.
Other things that I really like about them are excellent dynamics and imaging. My system images well anyway, but the Heimdal's take it to a new level.
They are expensive, but I plan to purchase them if I can get them at a good price.
