Hi, almost every respected audio amplifier manufacturer and manufacturers of power conditioners are talking about power factor correction. Could anyone please elucidate what power factor correction is? How important is PFC? Does PFC also prolong the life expectancy of a power amp? Doesn't common AC from the wall outlets without PFC no longer sounding good for high end audio nowadays?
Will a power amplifier with a power factor of 1 sound better than the same power amplifier with a power factor of 0.89? If this is not the case, so why bother?
