Considering the price range, I suggest you audition the ff. brand new models at Spectra in Parksquare:
1. Denon AVR-1603 at P18.5T
2. Yamaha RX-V430 at P15.0T
3. Harman Kardon AVR 1550 at P16.0T
I personally use the Denon and I'm very happy with it, clean and rich sound. A friend of mine has the Yamaha and it sounds great too, natural and powerful. I heard the Harman Kardon only recently and it sounded great with Mission speakers, rich and warm (I understand you will be matching them with Missions). It depends on your taste and what you'll be using them for. If you're more into movies, get the Yamaha. If you're more into music/concerts, choose between the Denon and the Harman Kardon.
