or you can get an electrician to wire a plug to 220vac.
That said I ran a power transformer for years and didn't notice anything with it.
I would not worry about a power transformer there is dozens in the grid just from the plant to your house with one most likely within a block of your house on the pole or on the ground in a big steel box, probably more then one. then you have one min in your amp. Every component in your system most likely has a power transformer so there are literally dozens of them in the power grid from the gen station to your wall socket then one in every component.
Only real concern is resale value IMO. but at that saving may not be a consideration. Also any competent tech can fix them and with that savings you'd have to have them fix it a lot before your paying more then the USA model. Bugs me when people here seem to think only a supper person or the manufacturer can fix my equipment. Audio equipment is not that hard to fix and any competent electronics tech can fix 99% of what's out there.
One last thing if the transformer in the equipment has a tap already for the 115vac then its even easier to change. Most likely if its a world selling unit it already has the tap and just needs to be wired in. IMO worth researching a little to see.
