Unfortunately mrdangum, i have to agree with the other posts here.
If upgraded HT means she wants a surround theatre experience, you simply cannot get around putting up surround speakers and running some wire. If she is willing to buy this expensive surround case for the tv and components, i'm sure she might be willing to buy some nicely finished speakers as well, even if they are surrounds with cable runs.
You can buy many types of good looking cables, flat 'under carpet' cables, etc. It may cost a bit more but my point is that you can hide cables relatively easily if that is your/her requirement.
You might want to have a look at some of the home theatre room designs that regular joe people have put together (try
hometheatreforums.com HT member pics)
Perhaps if your g/f sees how some people have integrated speakers and equipment into a nicely laid out room without ugly looking cables everywhere, she may come up with some new ideas of her own about what she wants.
