Something else to keep in mind - If you listen to multi-channel music, or want to at some point, sometimes people use di/bipole speakers on the sides, then put direct radiating (traditional type) speakers in the rear. These rear speakers should be used for the multi-channel music.
Also, it may be advantageous to have the rears equidistant to your primary listening spot. Since the 5900 has time alignment for both SACD and DVD-A, perhaps this is of no concern.
For further advice, I think the THX and/or Dolby Digital websites have information on speaker placements.
