I think you've answered your own question. Among the audiophool community,there are people who swear that soaking a power cord in liquid nitrogen willre-arrange the "grain" of the copper and yield better sound. Well, god bless 'em.If a rectifier can produce clean DC current, it's good. A failing rectifier can let 60 or 50 Hz seep into the signal chain, but if the DC is good, that's all you canask of it.
