VonSchewikert VR4JRs can be purchased used in your range and they meet your wife's criteria, which are also mine. These work especially well since the have a wide sweet spot, wide enough for two listeners side-by-side. They image especially well if you add front tweeter diffraction dissapators for about $50. like the ones reviewed here:

Along with the VR4JRs rear-facing tweeter set to minimum you have a wide, deep soundstage, holographic imaging and deep, powerful articulate bass.
I'm running tubes as well and this is as close as I've heard at home to a live performance in my living room. And, as good as it sounds in the room, from the adjoining room it sounds like you've got someone gigging in the next room.
