The ”sweetspot” in the Nordost line of cables

What do you guys think about the Norse 2 line specifically for power cables? I have the Heimdall 2 but don’t know how much better the Frey/Tyr 2 can get.

My previous Nordost PC frame of reference was the Brahma and Shiva lines, but they are well in the past.

Thanks for all your detailed and informative replies. The Valhalla and Odin are more than I’m willing to pay. Would Shunyata Alpha be a better match than the Nordost Leif cables?

Or would I be better off keeping my old cables?!

"Would Shunyata Alpha be a better match than the Nordost Leif cables?"

Your ears should be the only one to tell you that, certainly not anyone here.

Only the power cable incorporates construction principles of the upper levels. That said, it is a good buy to find out if Nordost catches your ear.

Heimdall is entry to the Nordost magic.

Your amp is at a level that shouldn't be dependent on cable brand. The "signature" should already be on display with your existing choices.

I A/B'd Shunyata Alphas, Heimdall 2, and Frey 2 speaker cables.  I chose the Heimdall 2's.  The Freys were a little better but not enough for me to justify buying them over the Heimdalls.  I wanted to like the Alphas better, but the Nordost won.

With Nordost your system must be on the certain level and you have to take time to evaluate these cables. I’ve tried Heimdal 2 and Frey 2. Frey 2 was better. But they didn’t wow me. The Tyr 2 is just next level in SQ. I’m running Tyr 2 XLRs now and this is the best my system ever sounded. There’s also a surprising synergy between the Tyr 2 interconnects and the Audience AU24SX speaker cables that I currently use.
Will most likely give the Tyr 2 speaker cables a try soon to see what they have to offer over Audience.

So the sweet spot in the Nordost line up is what sounds best to you in your system within your budget.
