I own the NuForce Icon that Rcrerar recommended and it does sound as if it would meet most of your requirements. It's beautifully designed, versatile and sounds great. No remote control and only 12 watts of power but in a smallish room with efficient speakers the sound is quite remarkable.
Another possibility might be the new Cambridge Audio Sonata system. I haven't heard it but it's small and looks to be designed with someone like your girlfriend in mind.
