Hi
Given that almost every device is going digital, better to go for an AVR which is 5.1 or 7.1/2.
Atleast you can connect all devices thru HDMI and your TV.....you can use the AVR in stereo to enjoy good music and HT mode for movies....
Given the output requirements, you need to look at mid segment or high end models from Denon / Marantz / Pioneer LX series, Rotel / NAD etc...it all depends on your budget.....
Depending on what speakers you are going to use, better to audition these avrs and decide for yourself....trust your ears.....all the best....which speakers you intend to hook up?
