Looking for an amp where I can use my Android phone as a remote?

I am looking for an amp that I can control (such as volume level) with an Android phone.  I have just purchased a media centre PC so am using that for my TV. I control everything using my Android phone.  It works over wifi by communicating with an Android server app I installed on the media centre.  Now I want to try and find an amp that can be operated from my Android phone.  Does anyone know of anything out there?  I really hate having different remotes and want to be able to control everything via my phone.
