What should I set the crossover of the EP175 sub at to go with the M22s? It goes from 60hz to 120Hz. I listen to alot of classic rock aka Pink Floyd, Dire Straits, Niel Young. And my next question is what is the best way to hook my cable box to the AV reciever? Optical or HDMI or some other way. And I have a set of Monster 5.1 audio cables should I use those for the audio on the oppo to the AV receiver? I am just trying to get it all figured out before I have everything in about 3 weeks and its all new to me. That Sherwood newcastle unit looks frustrating to get all set up right after reading the instructions JEEEEZ.
