its true yamaha are indeed the best in receivers, in speakers u might wanan go for the cheap ones becuz ur budget is pretty low, or there is a sony home theater system around 28k thats preetty fine and is near 600watts i think, personally home theater systems, u shud invest alot because its a 1 time investment, it suggest u the sony one or u can try a samsung one which has a hdmi port too, its also 28k but less sound quality than the sony one
try ur local samsung and sony shops
