Big Aura:how very graphic! I'd sooner get the centre speaker than the sub, and add to it in time so you eventually get a 5.1. Personally a 3.0 with strong speakers would give a better sound... That said, there's little point in a 7.1 multichannel amp if you don't intend to use it all.
Until I buy a place that I can hack the walls up in. I am not allowed anything more than the 3 front speakers and a sub. The wife detests wires.
Might have a look at the centre speaker, although I am restricted in space a bit (unless I wall mount it). I'll post a pic of my current setup tonight.
Thanks
