What is the smallest form factor 5.1 amp out there?

Wifey came to the conclusion today that her kitchen needs better sound than what comes out of her TV. So, still in the box are a set of Def Tech 600 speakers and the little sub that'll be just right for her 120 sq ft kitchen. BUT... her idea of a reasonable component size is the same size as her AppleTV. She bitches about the space that is taken by the Direct TV receiver.
Need: 10 to 100 watts per channel X 5 and sub out. Optical in. That's about it.
Anybody have any leads? I haven't shopped around at all lately for audio gear.

Here's her space... http://www.avsforum.com/t/743823/ok-your-lcd-you-tell-me-got-a-new-one-post-it-here/1470#post_22651693

Thanks Chris, but I have a Neo HD too, and She hates it, and too big. Ross yep, She wants 5.1, and she's NOT willing to give up any more of her shelf space, but maybe I can get her down to stereo, it would be a lot easier. She does't want the in-ceiling speakers I got her either.
The WAF is all important on this one, note no back-splash yet, nothing has been found that says wow yet to her.

DUH!! That's the solution, Thanks! There is a closet directly above her shelves and dropping wires in the wall wont be too bad of a PIA right there, I think . Now to get the DirectTV unit up there too, she would be much happier.
Here's the other side of the kitchen...
