Bed room systems?

Most will have their main two channel systems. Others may may have secondary home theatre set ups as I do too. Some have a combined approach. But what about the bed room? I use an Ipod and the wincy altec lansing portable speakers which are fine when I am on the road (and I am a lot) but I am considering something for the bedroom. Paramenters I am considering are reasonable cost, small footprint/space requirements, doesn't have to play lound not deep bass is a requiement but should sound good at low volume levels with capacity to reveal inner detail, remote control operable, wife acceptance level should be high, if tubes cannot get hot, digital only but with SACD hopefully, no thick power cords, speaker cable or interconnects, ....

any ideas or examples?
