<font color='#000000'>I was just looking at these 3 receivers at the yamaha website and was surprised to see very little difference between them.
The RXV530 at $399.00 has 5 channels @ 75W per channel.
The RXV630 at $499.00 has 6 channels @ 75W per channel. This is the ONLY difference between the two.
The RXV730 at $599.00 has 6 channels @ 75W per channel.
It adds on screen display which is the ONLY difference between it and the RXV 630.
Other that these receivers are identical.
I agree that the 6 channel is a big difference if you have a 6 speaker system, but normally you would find greater differences between models like more audio/video inputs or more power, surround modes, etc.
It just strikes me as funny that the only difference between the 630 and 730 is OSD.
BTW, the 730 is on sale at Goodguys for $499 right now, which makes it the same price as the 630, but the bottom line is if you only need 5 channels and don't care about OSD you get the exact same receiver for $200 less ($100 now).</font>
