With the premium member/vendor subscriptions, I think Goob should contact the owner of homeaudio.com, and buy it. It's not being used and is obviously just waiting to be bought.
That's the only thing I could find out about the domain. I mean, I would buy a subscription to here and there if he did it. I'm sure others would do the same, and he could have similar vendors offering different services/products(cabinets, home theater subs, etc).
If Goob doesn't want to buy homeaudio.com, he should buy homeaudio.org or .net. I think it's time for Goob to expand, regardless. I don't think this one forum is enough for us, and I think the activity is because of the lack of space, not vice versa.
