imo, parang mas maganda pa rin yung 608. THX certified na and w/ banana plug inputs. i think yung plus lang ng 509 is yung network capability.
Hey dude!
I have a 509 and it has Banana Plug terminals too.
You just have to remove the safety covers put by Onkyo EU.
Another difference to note is that 608 has 7.1 audio while the 509 has 5.1.
I was considering the 608 too, but when I heard of the 509 being available already, and I have a small HT area lang naman, I went for the 509.
I am currently a very happy 509 user.
I'll consider upgrading again, after I've upgraded to a bigger HT area.
Btw, the Network feature is good because I can access my Audio on the Etrayz DLNA server and I can use my iPhone as a remote control.
