Yes, the Nordost speaker cables gets very expensive when you move up the line. I believe the next step up for you is the Norse 2 series. The only Nordost cable I own and tried was the Red Dawn Flatline IC.... I used it between a separates combo I just sold, but am now trying it out on my Rega Apollo player.
I bought a brand new Rogue Sphinx integrated amp which has been getting very good reviews. So far I still breaking it in and evaluating its sound
Let me ask if you don't mind, I am toying with changing my speaker cable. My speakers are Acoustic Zen Adagios; I am considering the new RD LE speaker wire. Unfortunately, I need about a 12 ft single pair and RD is expensive stuff, so I wonder if dropping down to Blue Heaven LE speaker cable would still deliver better sound than my Audio Art SC5 which is their entry level speaker cable. The SC5 sounds good, but I want to push the envelope to get the best sound from the Adagios without dumping a ton of money into speaker cable.
Sorry, I could not be more helpful. However, if you have specific questions about the Nordost upper level reference cables, call the company and ask for Paul, He is very knowledgeable about the new cable products
