I recently got into home cinema with a Marantz sr4300, tosh sd220e and a mission cinema 6 pack through my Sony TV. I used the amp and DVD with a mixture of different hifi speakers before the missions and the sound was ok (Pair of Heybrook HB1's, a mordant short ms10i centre and a pair of eltax floorstanders for the rears with no sub). I figured get a dedicated surround package with a sub, so i got the missions. Ok effects steering and rear effects are good but it doesn't have much bite to it. I basically have to upgrade to 6.1 or there's no point having the marantz,(I'm waffling a bit here guys so bear with me!) instead of getting another model 70 monitor off ebay (i've seen a couple), should i get a mission dedicated centre and put the other monitor as the rear, cos there's always loads of centres on ebay. If so which centre should i get and will it give the system a bit more attack and presence? phew sorry that took so long to say.
