I am currently in the US, and can get the AVR230 for $412 or the AVR 330 for $542. Even allowing for import duty and VAT this offers a significant saving over the best prices I have seen in the UK (£499 and £599 respectively), however they are obviously US spec 110V models. Can anyone tell me if it is possible to convert them to work in the UK, or if a step-up transformer would impactperformance? Any help would be much appreciated, as I return tomorrow evening so need to move quickly if I'm going to get one. Thanks in advance!
