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.
