the Harvey Norman Yamaha set comes with Receiver: RSV -465, NS8390 P60B @ RM3399(?), I was considering this as well, can I get it cheaper if I get it outside? How will this set perform? Or is there any alternatives?

I kinda like the 465 with the 4 hdmi inputs, so I think I will get this avr, what other 5.1 can I pair with avr? Can I just go with a 2.1 setup with 2 floorstanders with a subwoofer?

this is what i'm thinking too, currently the space is not too ideal for 5.1 setup, in the future if i change the home theater place then i would get the remaining speakers.

so it is recomemded to get all in the same model/series/brand?
