I currently have a 5 year old Mission Cinema One package (700's, 70c1 and 70's I think it is). I am moving and have a loft room which is all nicely done with minimal stuff in it which is 15'8 by 12'4 theres a hatch in the rear corner which means I need the rears to be satellites on the wall as there's no space for a speaker stand. Currently have an old Sony STRDB925 amp which I am thinking of upgrading to the Yamaha 750. Bearing in mind the speakers I have would it be better to get a whole new set up like the Aegis packages? I quite fancy floorstanders at the front as I want decent stereo, would it be a bad idea to have floorstanders at the front and satellites at the back in terms of balance? Could getting new Mission centre and floorstanders at the front be an option and keeping the current satellite rears?
