Here is a comparison on two of
Onkyo's most popular receivers, the
TX-SR507 and the
TX-SR607. The
507 is a
5.1 channel receiver, whereas the
607 is a
7.2. The
507 is rated at
80 wpc, the
607 at
90 wpc. The
507 has
4 HDMI inputs, the
607 has
6 HDMI inputs. The
506 does not
upscale incoming video signals, the
607 does. That's pretty much all of the differences between the two. They are both excellent receivers.
Onkyo has always been known to give a lot of value for the buck. I don't think you could go wrong with the
507, so long as you don't need
7.1 or
7.2 sound.
