Look into the Equi=Tech Q series balanced power conditioners. I have experimented extensively with balanced power, trying various isolation transformers from the major transformer manufacturers. For the past 4 years I have been using a DIY balanced power conditioner with separate trsnsformers supplying my analog and digital components. I am using an Equi=Tech Q type isolation transformer for the analog components. I experience no current limiting, and there is a clearly noticeable improvement in my amp's low-end performance. I can't imagine ever going back to plugging directly into the wall.
