Anyone compared Nordost SPM to the Frey intercons?

System comprises the following- Marsh a400s amp, Pass Labs X2.5 preamp, Cambridge CD player with hot-rodded Channel Islands DAC, Equi=Tech 1.5Q & PS Audio Ultimate outlet. Interconnects are Nordost SPMs, Harmonic Tech Pro SilwayIII, digital cable by Nordost (wow!). Power cords are Nordost Shiva & Vishnu. Can't forget my ageing,but beloved Vandersteen 2ci speakers.My wife and I lsten to all types of music. any insight will be appreciated! Thanks
