Purchase European 220 power cords and power conditioners in the U.S.

AREUSK5FD is $997.00 plus shipping.  U.S. model you can buy online: https://www.onfilter.com/product-page/arn5156fd  but not the European models.

there are several adapter threads here and the common theme is: adapters and converters are generally for cheap appliances, no such thing as audiophile converter/transformer. I am ignorant about the effects of power on amplifiers but if it's a big deal to you, I would want to replace the power supply unit in the amp at your destination.

The Swedish company Entreq is highly regarded for its range of cables and I have used them for many years. I think they still have a Canadian distributor but you can check on their website.

Puritan Audio in the UK which I also use is another I can strongly recommend but I think you would have to contact them in the UK

220 volts? Incorrect. The integrated European power grid has been supplying a uniform 230 volts since 1995, but with tolerances: Previously: 220 V ±10%/ i.e., 198 V to 242 V. Today: 230 V ±10% heisst: 207 V to 253 V. However, most devices are designed for 230 volts. The UK probably still has 220 volts and 3-pin plugs. Schwankungen sind aber selten, nur für die, die viele Industriemotoren und -generatoren in der Nähe haben.

Eastern Europe has 220 Volts
