I'm new to the whole surround sound thing and was wondering if anyone could shed some light. I have been a two channel junkie for a long time and decided to venture into surround only recently so I bought myself a Yamaha DSP E800 receiver which feeds my mains (mission 753's) via my amp Musical Fidelity A308, the rears older missions, but still up to the task, and a heybrook 200 sub. I haven't, however got a centre speaker and have assigned that to the mains. With DVD's especialy on DTS the sound is fantastic, and could frighten half the street, although I've only listened to out of the box set ups before but there's no comparison. However am I missing out on having no centre channel? If so what do they add and should I be looking for a mission centre or would another make be ok?
