Hi im upgrading my home cinema very soon and after browsing a russ andrews catalogue im interested in this 'purified mains' they glorify so much about. My question is what are peoples first hand experience of these and which is more important, the mains block itself, or an equipment lead. There is a guy on ebay who is selling various cables and blocks at different price points, and his feedback and general products look very promising. Do i spend more on the block or cable as i intend to get both if they are worth it. thanks guys.
