Depends on how long you will be there? Is this a short assignment or are you moving permanently.
If you're moving permanently I would recommend getting the transformer taps on your amplifier reconfigured for 220/240 VAC (assuming its a multi-voltage transformer). I say this because the performance of your amplifier will probably suffer if you use a step-down transformer instead of re-configuring, especially if its a high current unit. If you're using a step-down, pick a good one that weighs approximately the same as your amp and is rated 0.5KVA above your amp's rating. Your digital front-end and preamp don't suck too much power so you can plug these safely into the step down.
