It would probably be easier to alter your service panel to provide a dedicated 230 volt line to your amp than to convert the amp to 115 volt.
In addition, the sonics of 230v should be superior to that of 115v.
I would send an email to the manufacturer regarding doing either option just to ensure you're not going to fry something.
