Someone above stated that Valkyra's were similar to the current Heimdall, and any of the newer Nordost line is superior to any of the old line except Valhalla.
Quite frankly, that is just not so, IMO and some friends, and we have had just about all the old and new Nordost lines, except Valhalla. They were used in revealing systems consisting of new Pass Labs pre amps and amps, Wilson Maxx II, Magnepan 3.6s modded, Benchmark DAC1, dcS, using Shunyata power conditioners and Shunyata Python and Taipan Helix power cords.
Quick summary: The new line is outstanding but Valkyra is quite a bit better than Frey. Frey is better than Heimdall. Haven't compared Tyr, though.
