At the moment I have a home cinema set up with 2 pairs of the AE300s (fronts and rears) a AE307 centre and a AE308 Sub. I may have the chance to change to a set which comprises a pair of Evo 3s (fronts) a pair of Evo 1s (rears) and an Evo centre. I would keep the AE308 to use with this set up. Would this change be considered an upgrade? Any opinions would be gratefully received.
