Sorry to hear of your situation. Prayers for a recovery best as possible and for you to assimilate easily into your new living situation. My mother did well for years in independent then transitioning in assisted living. The social interaction and activities kept her sharp to 91.
My recommendation in you more than adequate budget would be a Mola Mola Kaluga one box with Vivid S12 bookshelf speakers. Alternatively, with the box, a Burmester 232 integrated at higher cost. An alternative speaker, also at higher cost, is the Sonus Farber Guarneri, also at higher cost. I have heard all combinations of the above and the will give clarity, timbral accuracy, speed, dynamics, staging, imaging, and excellent bass to about 35-40Hz so you should not miss much. Good luck.
