i just ordered the Aune MKII and reading the forum. It seems AC adapter 15v 1A aren't so easy to find in my country. Is it ok to use a 15V adapter with 4A or 6A?
Newbie question probably but i am affraid to burn "my precious".
Yes. You can always use power supplies with extra amperage. It is the same idea as using a 100w amp with speakers that have a max rating of 70w. The overhead is there to keep things clean and avoid voltage drops due to the component maxing out the amperage that the power supply can provide.
