Thank you Joshua for your comments on Wireless.
As of now nothing is fixed. So rather making it more complex by adding features and brands. I decided to cut short as much as possible, when I read lot of reviews, I understand Onkyo has reliability problems. I will be going back to India in next 6 months. So I really do not want to take any chance on my receiver. If anything happens, no one can repair. I know Yamaha have there service shops and even Denon has some authorized shops in India. So I decided to stick with these 2 brands.
I am not worried much about features like wireless or video up scaling etc. I need a decent quality sound.
So need your help in finalizing my receiver.
