I'm moving from London to Stockholm next month and wondered if there is a smart way to handle power sources for my HiFi?

Currently only my TT has an external PSU, all other items are mains powered via a couple of powerboards plugged into the wall. Amp is directly plugged into the wall.

Simplest solution would plug adaptors on the powerboards. What's the opinion on using plug adaptors?

Is worth spending getting a better quality powerboard - currently they're quite basic, fused / surge-protected. I could buy a better UK powerboard and change the its plug to an EU fitting.

Is there a better option still that is not too expensive? Any advice greatly appreciated.
