The dedicated AV room isn't even built yet...let alone properly planned.
I'm pretty sure it will have another PJ in it. I've got Mrs Woz's ok on this as she enjoys the big screen movie experience, and we got money for my current installation in our house sale. It probably won't happen until next year though.
The room will definitely have my B&W603s, and my B&W centre channel.
I'll be using my NAD C370 to drive the 603s as I do now. The rest of the kit is up in the air to be honest.
As far as the plasma goes, I know what you're saying. I wasn't planning on getting any flat screen tech for a year at least. If you look at the pictures of my current setup, there is a big mirror behind where the screen drops. The long-term plan was to replace this mirror with a flat screen, but we decided to move house and put the kybosh on that.
The new lounge is intended to be a lounge first, with the telly as discrete as possible (whilst being big enough to see! The room is 5 or 6 metres across each way). We're getting it decorated and so the cabling will have to be put in early, and we want the display up soon as well, so we can't hang around. I'm tempted to ignore hi def because it's not going to be huge in broadcast telly for a few years, by which time the plasma will probably need replacing anyway!
