I guarantee you'll hate this response. Getting those, or any for that matter, speakers set up in a room that is 10x8x9 is a major undertaking if you expect to obtain high(er) quality sound, especially a full range speaker not intended for such small space. Room acoustic's and speaker set up will be a bitch. I would think that your choice of an amp will be the least of your problems, and considering the room's size even a small amp will allow you to overdrive the room easily.
Assuming that you do not have an amp yet why not just buy a smaller integrated amp (tube or SS) which has high resale potential and play with set up and room acoustical treatments to see if the room can be used at all with these speakers. The are fine speakers but I don't think they were really intended to be used as nearfield monitors and that is what would work best in a room that size.
FWIW.
