System: Mordaunt-Short Avant 906, 905c, 902. Yamaha 640SE. I have had my setup for about a year now, and it has just occured to me that my rear speakers (902 standmounters) are probably not even run in yet. Although I use my system a lot (on average about 3-4 DVDs a week), my rear speakers dont seem to get much use, apart from films like LOTR where a lot of info is sent to the rear channels. My front 906s and 905c I think are well bedded in now as they obviously output constantly during films and music. I am just wondering how long it usually takes for rear speakers to be ran in and reach their potential. I even thought about moving my 902s to the front for a while to give them a good few hours solid use, but I could do without messing around with my cables again. My 902s are on 'empty' Apollo Olympus stands at the moment. Would I notice much difference filling them, even though they are just the rear effects channels? This may sound like a daft question, but would a better amp help? i.e. would the effects steering be more accurate, thus bringing the rear speakers into play more? Any help appreciated.
