Nordost has announced the Series 2 for the Norse lineup. With that there are plenty of bargains with the originals from authorized dealers. Musicdirect has some brand new ones for 1/2 price.
I personally think you will be quite impressed with the Heimdall speaker cable. I had a demo case about a year ago and for the money Blue haven and Red dawns were not bad but like you noticed lacked the good clean bass and I found both to be bright (not harsh). Baldur was a little better in both the bass and highs but still not great. The Heimdall's and Frey's were a lot better (more 'air' between the instruments and vocals). I had to 'squint' to hear the difference between those 2. Regardless I went for the Frey's and still have them. My local dealer hasn't loaned me a demo case for the new series 2 yet. They are supposed to be a lot better (pricier too). I've also heard Nordost will not offer bi-wire configurations with the new series 2.
