Update. I'm more confused that ever.
I have some advice saying always go with direct speakers for a 7.1 system because you get plenty of surround feeling with 8 speakers and better clarity than with dipole/difuse set-ups. Makes sense to me, particularly if you mostly listen to music. The Bravos, which are the direct option, also offer a very discrete, flexible and easy to locate design.
Yet, when I look at a long list of folks who are using BA speaker set ups, 75% of them have the dipole/diffuse speakers and love them, although this is generally in a 6.1 or a 5.1 set-up. (I have some interest in this approach because I used to have maggies, which had great "live" presence because the signal was emmanating from the front and rear of the speaker creating a lot of depth to the audio.)
Without being able to audition these, it's difficult to make a decision. Any advice on pros / cons in general about dipole/diffusion vs. direct would be appreciated.
