Have not tried the Yamaha but i do have Samsung HW-K950 ( the price is ~ RM4000 ) after discount from 11street, for sure cannot compete with normal speaker+atmos speaker but you do have to remember there is no way u can get atmos sound system for only RM4k, and not to mention no wires running around ( important for me as i do not want to hack my walls to hide the speaker wires ). The sound is pretty awesome and i am very satisfied with it, easily loud and powerful enough
