In addition to the good advice given above, you might want to narrow your search to speakers which provide a boundary compensation adjustment for positioning them near a room boundary. I find that one of the biggest issues with the waf isn't how the speakers look but where they are placed in the room for the best sound. It's pointless to buy a speaker designed to sound best in free space only to put it right against the wall on a shelf - bass response and imaging will suffer. On the other hand, having the speaker three or four feet into the room on stands and easy to trip over just to sound good will not win any kudos from your spouse.
Your Sansui should easily drive any modern reasonably efficient speaker without clipping especially if it's been able to drive your 901 "watt sponges" all these years.
I would look at monitors like the Revel Performa M22 or the Snell J7 which both offer the room boundary compensation feature.
