I'd be very grateful for some advice on speakers. I want to upgrade to a 5.1 surround system which will be used for films and music (40/60). I don't want to compromise too much on music performance so want to keep my Mission 760is as fronts. Can anyone recommend centre/rear/sub which will integrate with the 760is? Buget is tight - say £200 I will probably buy a Pioneer 565A universal player and a Sony STR-DB790 amp to complete the set up.
