digital home theater setup

[cryptonz]

hi guys, i'm newbie here. and i am very thankful to be a member here.

i just want to ask, i am planning to upgrade my logitech z-680 speakers to a much more loundness than my current one in terms of playing dvd movies from dvd player with digital out (coax/optical)

what amplifier i need that also have coax/optical input
must have 2 front speaker, 2 rear, and 1 center, and a sub woofer to play a much better so called "home theater" setup.

i know you guys can much knowledgeable in these setup so anyone can help me would greatly appreciated.

i'm planning to place this system to our living room quite a bit large for a z680 system (for pc). 500w rms and total of 1000w rms peak.

maybe the system i just need around 1000w up if there is such ampli and speakers that can handle and it's digital too.


thank you very much.
