Hi all, first post and already starting with problems! I recently moved from Canada to the Czech republic going from 120v/50hz to 230v/60hz (correct me if I'm wrong on the frequencies). Regardless, I brought over my pair of event 20/20bas monitors that I simply couldn't let go hoping to get to use them here. I bought the following step up/down transformer: http://tinyurl.com/7thjr except at 750 watts. I'm getting a fairly noticeable buzzing from my monitors, I've tried unplugging 1 to see if there was insufficient wattage in the converter, not the problem, still buzzes. It becomes basically inaudible if there is music playing, but I still *need* to get rid of it because I just hate excess noise. I was wondering if maybe there was any kind of mid-chain solution that I could buy, or possibly some recommendations for a new converter or other options? Thanks for any help!!!
