Can certainly vouch for focal speakers - the chorus series are simply awesome. I also had an energy subwoofer (before upgrading to focal) and it punched well above its weight. West Coast HiFi carry both brands, although the energy speakers are considerably cheaper.
I run a Yamaha amp - enough power (140w per channel) + 8x HDMI ports...so don't need a switch anytime soon! Again West Coast HiFi will do good deals on the Yamaha amps - but also worth looking at Eastwood HiFi (who also do Paradigm) - you can get a realy good deal, but you need to factor in shipping costs:
