Thank you everybody for your insights. Here's my current thinking - let me know your thoughts before I pull the trigger! smile

I have let go of my original idea of LFR1100s for the fronts, instead looking at M100s. I don't think that my room dimensions and quirkiness can do justice to the LFRs in terms of the distance from the wall they require. (Something to look forward to if/when I move to a bigger space!)

So in summary -
- M100s for the fronts
- VP180 for the center channel
- A pair of M5's for the sides (remember this is for discrete multichannel music as primary objective)
- EP500 subwoofer
- Potentially QS10's for the rear surrounds to complete a 7.1 setup for movies.

I'm expecting that the M100s, VP180 and M5s will be well matched for multichannel music - thoughts on this?

Thanks guys
