Thanks bigjohn.
I actually have M60 as front and M3 as surround for my HT. Now i have to move HT to another room so that my family can enjoy watching and my current room will be my dedicated 2-channel music only. That's why i want to cut down the budget with decent HT. (spent too much of my hard earning on 2 channel gears already...:)

I may look at QS4 or even another pair of M3 for surround.
