Since you are located in Europe 230V/50Hz operation using a step down transformer will not be a problem because Japan uses both 50Hz and 60Hz at 100 Volts. Japan is the only country that uses 100V 60Hz/50Hz. All transformers are designed for both 60Hz/50Hz.
I have purchesd Three Luxman and and one CEC from Japan at half the price in USA. The Luxman L-507U you can change the 100V to 115V or 230V by just moving the jumper from 100V to 230V. Also disconnect the wires that is connected from 100V/115V to 230V operation, The transformer one section works for 100V/115V and the other section is for 230V/50Hz operation. Also you need to replace two main fuses to 250V. There is no such thing as Grey amplifier import both Luxman and Accuphase are super high end custom made Japan product.
