Thank you and the voltage converter may indeed be an added source of noise. But there are quite a number of used 508 for sale already in Europe. I saw some at hifishark and German classifieds, and like you said, these are 220-240v versions. Just this past week another used 508 is available in AudioAsylum USA for $3,700. I'm actually looking at acquiring the 508, to have it alongside my 518, and I don't mind a pre-owned unit, that's why I have been scouring around used hifi classifieds. However, I'm still scratching my head why in the short time that the 508 has been in the market, there are these owners already selling their units.
