Nordost Dawn LS Series Speaker Cables

I was hoping to get some feedback from some other members that own/owned or heard the Nordost Red Dawn LS Series Speaker Cables. I just bought a set and added the older Nordost Red Dawn Jumper cables to my Martinlogan Spire Speakers that I drive with Decware Tube amp and preamp products and an Ayre DAC and I am blown away by these cables. What an incredible upgrade. I can't believe there are still people out there that actually really think that cables don't matter and really believe it. How can that be? Do these get better over time and more use? Also, I tried the Nordost recommended diagonal bi-wire/jumper cable set up which seems to work great. Any advice or feedback would be appreciated. I am so happy with these I may have to try the next step up in the line but with this manufacture it can get pretty costly and quick. Thanks
