B&W Speaker Placement


I am very new to the "high end" audio game, and would welcome any suggestions on speaker placement for my system. First, my room is 15 X 19. With the listening position 13Ft. from the speakers/TV. My system is as follows.
Lexicon MC1 Processor
Marantz MA500 Amps (5)
B&W CDM7nt (front)
B&W CDMSnt (rears)
B&W CDCCse (center)
Pioneer Elite DV-37/DVD&CD
Musical Design/Aura Speaker wire (are these decent?)
This system is very clear & detailed on movies, however on music, I dont seem to get the WIDE or DEEP soundstage that I want. Any suggestions for a rookie would be welcome.

Thanks for the info. Moving them out from the wall gives me better, quicker bass, and a little better depth, still not very wide with the "stage". Do you toe your speakers in? Also what speaker wire do you use.Thanks
I recently changed from Radioshack Megacable 12AWG (25 ft) to Kimber Kable 8TC (8 ft). While the change definitely gave me clearer presentation, I would say the sound stage (at least for my case) was more to do with how far the two front speakers were apart. I did lots of experiments with the speaker placements, and the sound stage was clearly related with the speaker distance. I do toe-in the speakers, which is for better focus.

Just to see how the sound stage changes, you can put your two speakers near the side walls. This will cause many other problems but to see if how big sound stage you can get.

If you haven't done so yet, I'd recommend you to check out Audio Asylum FAQ. Go to http://www.audioasylum.com/, and then at the top right corner there is "Audio Answers". Click it to go to "Speaker Positioning Resources".
Hey, Thanks again. Looks like I need to experiment ALOT with placement to find the correct position. Great info @ Audioasylum as well.
I've done a lot of experimenting with speaker placement and find that I get the best results spreading the speakers apart as much as possible while keeping them away from room surfaces such as side and rear walls. Also I have found that the sound stage collapses with even a slight toe-in so I have the speakers facing straight out with no toe-in at all. My room is 13 x 21 and I have the speakers on the short wall a little over 5 feet from the rear wall and roughly 2.5 feet from the side walls.
My speakers sound best about 1/3 into the room with a listening position about 1/3 from the back wall.
