Rhodium vs Gold AC connectors

Hi dear fellows.Does anybody tried these type of connectors in power cords?In my case I don`t know which could be the differences in sound performances between them.I heard that rhodium connectors have more extended hights frequences , more airy and fluid than gold connectors, but also that they can produce a non-lively sound, with too much control.Regarding Gold connectors I red that they produce a warmer sound, specially in the mids, but with not so much detail as rhodium.Is it true?I will appreciate your comments to make a proper decision.Thanks in advance!Raf
