    I know there's a lot written about the benefits of Cat5 and T & E, infact there's almost too much to filter through so I thought I'd ask this (simple) question!!

    Why twin & earth? From reading through its all to do with the CSA of the cable hence needing three lengths of cat5 per speaker (double for bi-wire).

    Would I be correct in assuming that it's to do with the structure of the twin & earth and the fact that the earth core sits between the 2 carriers? In other words can you use standard 3 core flex?

    We are embarking on a new house build which will be wired for multi-room A/V and I don't want to braid hundreds of metres of Cat5 so I'm thinking T&E is the way forward...

    Cheers!!

    There is no simpler way to justify T&E, other than its thick and cheap! The earth core will do nothing but make stiffer to install (sometimes good or bad!)
