Octavian, I see that you're more interested in what mode of play to try first rather than a specific CD, but I'll also suggest that for a CD I suspect that you have one or more versions of Enescu's Romanian Rhapsodies and that would certainly be appropriate to baptize your new speakers. Then since it'll be the Christmas season, as I suggested in the Christmas CD thread, playing the Nutcracker is a must.
As to the mode of play, none of those that you list. You need to give those QS8s some surround sound to work with, but use Logic 7 Music mode to steer the ambience contained in the CDs to them.
