To be honest, the only thing I need is for my speakers to be powered so they can shine to their full potential. I only need something that will have my movies and video games sounding beautiful on my speakers. I will only be using these two B&W 685s and nothing else. My budget I'd say is $700. I started looking at the Harman Kardon HK 3490 but in the past I was also looking at the Onkyo 818. Would the Harman Kardon 3490 be a good choice, or should I look for something that has room correcting software like the Onkyo 818 with the Audyssey? Again, I will only be using two speakers.
