Not sure if you are still in the market, since your post is a few months old. I recently demoed the SPM, Valkyrja, and Valhalla speaker cables with my WATT/Puppies. Definitely noticeable steps in performance between the models. I also asked my wife (a patient non-audiophile) to listen to give me a reality check. She also immediately noticed the differences.
I'll describe the sound of cymbals as an example. With the SPM, they sounded good, but truncated and muffled compared to the other two. With the Valkyrja, they sounded great - more air and longer decay. With the Valhallas they were even better -- the sound lasted longer and had even more detail.
Personally, I was hoping the difference wouldn't be that noticeable, so that I could get the Valkyrjas and spend less. However, as many reviewers have said about the Valhallas: once you've heard them there's no going back.
You've probably heard that Valkyrja is being discontinued and replaced by Tyr. At CEDIA, a Nordost rep also said that something better than Valhalla is on the way.
