I've sort of decided on replacing the telly with an OLED 55EF950V and a set of 3 Cambridge Audio Minx Min 22s and a Minx X201 sub (which will live on the bottom shelf of the A/V rack). We're having quite a bit of work done on the house over the next few months and I think we'll get a custom set of shelves built in that alcove once the rest of it's done.
I have to be VERY careful with this thread now. The Internet telling Mrs b0redom that she's right is a very dangerous thing!
