220v / 110v - Anthem STR Power Amplifier

Hello all, I have an Anthem STR Power Amplifier to power my Focal Sopra N2 speakers, and I love it. I live in Miami now but I will be moving to Spain in the next few months. I am told that they cannot do anything to transform my US 110v model to a European 220v model.   So I am wondering if any dealer out there in the US may take mine as a trade in and sell me a new 220v version.. Probably it's hard to get a 220v model in the US... but putting it out there. Thanks!
