You are supposed to keep the three fronts similar. I've always done that (Linns, VMPS, Salks). However, go ahead and try it, if it's not too expensive, and see what you think. You could always buy matching R/L speakers after trying a center channel. I find that I can't tell for the speakers I've used for surrounds any difference, even though I've combined Mirage surrounds with Linn/VMPS/Salk fronts and VMPS surrounds with Linn rears. I don't play music, though, in 5 channel.
