If you are going to use your system for multichannel audio, I think the setup you are considering will be ideal. directing the surround channels from a 5.1 DVD-A or SACD to M2's positioned behind the listener will sound much better than using QS8's. If you are definitely not going to play DVD-A or SACD, then the idea of getting the M60's for fronts and possibly getting a third QS8 down the road for the rear channel is a viable one.
