Pass labs aleph 0 monoblocks .... convert voltage?

Hi guys!... any aleph 0 monoblock owners?... have a chance to buy a very nice pair locally, only issue is that they are european voltage, and here we use 120v.... 

anyone knows if they can be converted to 120v?... or am I stuck to use a voltage converter with them?, if the latter, which converter do you recommend? 

Thanks!!
