I have a 2 gang mains socket behind my hifi unit and I plan to fit it with surge protected sockets. Clearly I need to expand this somewhow as I have more than 2 things plugged into it. I have looked at 6 gang extension blocks but the hifi ones appear to hundreds of quid. Now, bearing in mind that my mains uses 2.5mm T+E, would I be losing anything by getting 2 decent plugs, two short lengths of T+E and 2 3 gang faceplates with plastic back boxes and making up 2 extension blocks. It would effectively be 2 spurs and each item would be plugged directly into the mains, without crappy extension block wiring. What would I be losing with this over a Russ Andrews power block (the one without filters). I plan to upgrade the actual power leads to my gear with decently constructed ones in the future. Any thoughts? Also, those mains cleaners that RA sell that plug in a socket near your gear, are they any good and are they as good as an actual mains filter block?
