Unique multi-national question. I have a Pioneer Elite HD RPTV (USA 110V model) that I am now using in Germany where the power is 220V. I am looking for the quietest, cleanest, and most consistent power transformer/converter to use with the TV. I've solved the PAL/NTSC issue and all my other equipment is dual voltage. Pioneer does not offer a 220 power supply for my TV. Any thoughts?
