advice on Dual Voltage

I just picked up a pair of Gallo Reference 3.1s to start building a small 2 channel system. I am looking for either amp/preamp or good quality integrated that is dual voltage (I am military and seem to spend a lot of time overseas!)
Budget is under 3K (Used or new...doesn't matter).
I had thought of getting a Yamaha A/V like the RX3900, but I don't want to sacrifice music quality. Any opinions on this would be very welcome as I can buy a dual voltage RX3900 easily.
Any help/guidance would be greatly appreciated!
I believe Creek Destiny Integrated is dual voltage. Also check out Linn amps, as these are more often than not dual voltage.
