Don't bother with Atmos if your budget is RM2k. Soundbar Atmos is just not just not Atmos, despite what marketing and the people who bought into them tell you otherwise. This will offend many but I've had enough of this soundbar atmos bullshit, but I'll be blunt - you're an idiot if you buy into it.

I think you should just buy an entry level receiver for RM1.5k then put the rest of the money into a pair of good bookshelfs. After that, you can upgrade slowly by adding piece by piece. Home Theather is a journey, not a one stop buy and forget it thing.
I would go for the C8 if you don't need any HDMI 2.1 features.

Get b9 instead with the similar price.

Thx bro for the recommendation. Before I read your reply today I so ngam visited Harvey norman in Sunway.
They do offer the free soundbar for me but they did not offer the $1500 voucher to me. The price they quoted is $12xxx bundle with sound bar and if you do not want the sound bar it will be $11927.

I also manage to contact other electrical shop, they offer $11,800 for me and if top up $1000, can get additional 3 yrs warranty. hmmmmm I am at a catch 22.
