I've recently imported some of the speakers mentioned in the title, and am now looking around for step-down transformers/converters that will let me run this system in the UK off 240V (the amp's power supply only needs the US 120v standard).

Has anybody else on these forums tried importing these speakers or the 4.1s? If so, what kind of luck have you had with step-down converters? I'm worried I've let myself in for a whole world of pain!!
