The ”sweetspot” in the Nordost line of cables

Find a dealer that can loan you the dealer demo cables.

I have demoed Odin II to Blue Heaven in my setup. 

With my level of setup-H2 from the wall to speakers. 

Personal cable reviews are just that, and not what you may experience. In some locations, it may not make a noticeable difference at all-my subs are plumbed with Blue Heaven-just because.

Questionable value at MSRP. If you can find used for 1/2 or less, great cable. One thing for certain- they make your setup look "high end" to your non audio friends.

“The Sweetspot in Nordost line” …Tyr 2 

However, with Maggie / Gryphon consider cables with PC-OCC copper….try Zavfino, Neotech or Audio Sensibility. I do not believe Nordost would be a wise choice. 

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?!

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.
