Paramasivam, If you want to spend real money then go for part purchase. Speakers from x, DVD/Bluray from y etc. I had once gone to buy a system. The guy there was very informative. He said these Samsung, Sony etc are commercial ones and in actuality will never provide the real effect like a Boss/ JBL speaker with a Harman Kardon system. He said if I have the money spend on this way rather than buying a commercial system. Only negative he said was these high end systems will not play mkv etc. Anyway paisa aayitte medikan irikuva njan :)
