check with cmy (sunway pyramid, one utama, sg wang plaza) or desa lowyat.
i got mine from cmy sunway 4 months back at rm 2.7k. desa offer me yamaha rv 1800 for rm 3250......tempting offer.

Already found the best bargain shop? mind to share? 

rm 1.6k for 4 months old stuff.gave him my mordaunt short 5 center speaker as a free gift as i'm not using it anymore.....kef iq6 in place now.
now i'm using pioneer lx 60 avr to match with my pioneer 51FD blue ray player.same color (black).

pioneer lx 60 good with the price i paid for.
i guess q accoustic will be a good match for ms front speaker.
for set up/tuning i suggest you do the manual with spl meter. should explore the hidden capability of 606.you could get the best gears but if the tuning and set up cikai one than you will start to upgrade your equipment.try to get a good installer with really can help you.
