Just got a rx-v2500 to power Kef Q7 fronts, Q4 surrounds, Q9c centre and Q95c rear center (about to upgrade to 2 KHT 2005.2). Running through the ypao, both sets of Q7 and Q4 both the wiring show as REV. The wiring is correct. Swapping the polarity, the ypao is then correct but the wiring is wrong. Any ideas??
