I have a pair of Mission M73's as fronts, a Mission centre (not sure of the model), some crappy rears that I've recently just acquired from a mate, and a Rel Quake all being run from a Marantz SR4300. Anyway, due to changes in furniture and decoration, I would preferably like some silver speakers all round suitable for both music and film, and the wife has even come round to the idea of changing them so am wondering whether I should just get some quality rears, or change the lot. The advice I am after is to decide whether the Mission M73's are good enough speakers that you wouldn't change them and just get some rears that complement them or to change them all (except the Quake) for something else that would give me more for the money. Budget is around £500 (ish). Had a look at some Kef Eggs at the Ideal Home Exhibition yesterday but have heard that they're not too good with music so not sure about them... Any advice appreciated...cheers!
