A:AnswerPolk, in my opinion. I personally have Klipsch satellite speakers and Polk sub. I think the combo is beast!!

A:AnswerI just take the advice of the experts at Best Buy. Just ask if they have someone that specializes in what your looking for. Don't just use the first person that waits on you
A:AnswerNot sure if I understand correctly, but you have to select which input source to listen from. Cable and Bluetooth are separate inputs and you can only pick one at a time.
A:Answer5ch stereo is a DSP mode to simulate 5ch sound from a 2ch source. If you watch a DVD/BluRay or off-air digital TV broadcast that has a surround sound audio stream and you have connected to this receiver through an HDMI port, you will hear the surround for your rear and center speakers that is encoded in the audio mix.
