If you need something to place your TV on other than the wall, you might as well make your new piece of furniture functional in addition to being aesthetically pleasing. That's just what Evesham is trying to convince you to do, sticking nice whole speakers into a TV stand known as the Sound Stage X1.
Do the speakers sound good? Your guess is as good as mine, but seeing the whole shebang is only $600, I'm gonna go out on a limb and say that the speakers aren't exactly top-of-the-line. Hell, nine speakers and a TV stand for $600? For all we know, they could be the same speakers that come on the Samsung K5, and I certainly wouldn't want my home theater based on that. Approach with caution.
