Looks really good! After reading many of @Skeptikal 's posts, I have stripped my system back to basics and I have to say the sound improved with every component I removed (ethernet switches, linear power supplies, expensive ethernet cables, expensive interconnects etc.).
My mains extension block is the final frontier! I have purchased all the bits I need to also make one of these; but, I am unsure how to wire it correctly. Would you mind pointing me in the direction of the posts you mention? Many thanks in advance 
ps. thanks for all the advice you share @Skeptikal. My system has never sounded so good!
