I have decided on the following system. I will be purchasing it through amazon.com as I can not purchase a silver coloured Yamaha Receiver in Australia. And generally it seems cheaper purchasing it online even after taking into account exhange rates and shipping charges. Receiver: Yamaha HTR-5760S or RX-V650Ti Speakers: JBL E150P (sub) JBL EC25 (center) JBL E20 (front) JBL E20 (rear) I am not sure of the difference between the two receivers. Both seem very similar. And I am hoping the sub I am getting will be sufficient. I am limited to US$1500 and the room size will vary. I am wondering also whether it worth getting the better receiver (HTR-5790S or RX-V750Ti). What do you think?
