If you will be using your amp in the U.S. or places that use 115V AC mains power you'll want to buy the amp directly from Lake People or through their U.S. web store: http://violectric-usa.com/
Amps purchased through Thomann.de are set to 230 V AC so in order to plug them into 115 V AC outlets in the U.S. you will need eo either use a step-up transformer or modify the amp. To convert your Lake People / Violectric amp from 230V AC to 115V AC or vice versa, see these instructions provided by Fried:

For those who are interested, I got in touch with Lake People and found out the following:
You can order the G10X amps direct from Lake People by emailing them at info@lake-people.de (don't forget the hyphen). You will get a 5% discount which will make the prices as follows:
(Current prices as of Aug 2012)
PHONE-AMP G103-S = 195,59 EUR
PHONE-AMP G103-P = 235,51 EUR
