I have been running a single run 6' pair of MAC CuQ speaker cables for about six months or so hooked up to my AudioPhysic Spark IV loudspeakers and i have come to the conclusion that they are not just a very good cable for the money but that the CuQ's are really very good speaker cables period.I run MAC palladium ICs from my CD source to my preamp and have just burned in a pair of the new cryoed Element twisted pair ultra ICs with a solid copper conductor and Eichmann bullet plug terminations between the preamp and power amp.the synergy with this combination of cables in my system is very nice indeed but i would like to audition a pair of MAC Mystic ICs between the pre and power amps sometime in the near future.Thanks....WCW III
