Jayh31, I heard and read the same before I bought the LFD Spirolink I and the LFD Hybrid Ribbon speaker cable pairs. Most of this reading came from the usual suspects (LFD dealers).
You have to let your own ears guide your decision based on comparisons to whatever it is that you have now. For me, the LFD Spirolink was a step up from the Tara Labs (Quantum III) I had been satisfyingly using for over a decade with several other amps (Acoustat TNT-120, ARC 100.2, Anthem Statement A2 and finally the LFD Mk IV). The Spirolinks were such a positive experience that in under a month, I purchased a pair of the LFD Hybrid Ribbons in England and these remain in my system now. It was a $350 learning experience (see listing lol). Have not heard the Nordost, so can't comment there.
