has anyone compared Nordost Frey ICs vs Valkyrja


I have the NAD M3 integrated amplifier connected to the matching NAD M5 SACD player. My speakers are Dynaudio Confidence 5, using Nordost SPM speaker cables. The interconnect I used so far is Audioquest Jaguar XLR, but I would like to upgrade to Nordost. I just don't know wether I should get the Valkyrjas over the Freys, or should I go the painful way and get TYR, maybe even Vallhalla. Would I ven hear the difference or does that require a whle new leauge of Nordost speaker cables? Any words of wisdom would be highly appreciated.

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.
I just picked up used Valkyrja ic, this ic in my system is spectacular. Way better than Heimdall ic I have   Not even close.
