2 Channel Listening Help For Denon 4308 - How to set up

[G9logitech]

Hey Guys -

I am getting confused on how to set up my Denon 4308 A/V receiver for 2 channel listening. I have Dali ikon 7's for front, dali ikon 2's for rears, dali ikon vokal two for center, and a Martin Logan Descent i subwoofer.

I have the receiver set up for blu rays and movie playback like this: In the speaker configuration set the speakers to small, sub mode to LFE + Main and the Crossover to 80 Hz maybe I should set my crossover for my fronts here to 40 hz since my front can handle down to 36hz regarding to the (-/+ db thing).

But im not sure about with cd playing with stereo/2 channel listening? I shouldnt have this set to LFE, right? So how do I do this then?

Thanks Guys so very much
