I have lived in countries using all voltages and it is a commonly known fact between amp designers that 220-240V regions perform better with most of their designs.
In addition, transformers that can cover the full requirement of the amp (hard to do, by the way) can provide more stable electricity and importantly de-couple it from the rest of the electrical installation in your home. I use transformers even at unchanged voltage to good results.
