120v to 240v Adapter to power Amp in USA

Right on the running a new independent circuit with 12-2 for a 240. That’s what I would do. 

Also, Stereo5 I co reacted Atoll and they said they can be made to order with the 120v, but once they figured out I was from the USA trying to order an amp from France that costs $1000 and have it be made with 120v they wouldn’t do it. They said to go through the only distributor in the US because they don’t want to circumvent him. However, he charges $1900.

I had already paid and everything and they made the dealer from France refund my money. All amps are made to order and they wouldn’t do it even though I said I would pay extra for the 120v option. Still waiting for the refund to go through. 

The distributor in the US is super nice and knowledgeable but I don’t think overcharging because you have a monopoly is very cool. These things go for €839 all day long all over Europe. 

I do believe that you can get an outlet in your home for 240 volt.  My dryer and other large appliances were plugged into them.  I don't know if that is the same outlet needed for your amp.

What you need is a voltage step up/down transformer/converter
