Which Harbeth Speakers

After a long search, I have decided to buy Harbeth speakers as well as the Luxman 505u and a Luxman dac or cd player. My room is about 12'by 20' wih 81/2 foot ceilings. The speakers will be on the long wall -- I will be sitting about 10 feet from the speakers. I listen to a lot of jazz, Miles Davis, Bill Evans, Stan Getz, classic Blue Note recordings, Brazilian, e.g. Ivan Lins, vocals Frank Sinatra, Nina Simone, Mel Torme, R&/b and Motown and African Music.
Any thoughts about which of the Harbeth C 7, m30.1 or shl5s would work best would be appreciated. Thanks to all who respond.
