I am looking at purchasing one of the following satellite surround systems for a Yamaha RX-V650 receiver. 1) Energy Take 5+1 (A$1000) 2) Energy Take 5.2 3) Energy Encore (A$1800) I would love to purchase the Encore system but I am contrained by my lack of money. So my question is whether it worth the extra money compared to the 5.2 or the 5+1 systems. Also, I know it comes down to getting out there and hearing these systems but I dont have a car and its thus very hard. Any opinions would be appreciated.
