Okay, so your complaint is the lack of inputs. Is it too late to return it to the Future Shop? Frankly, this is something that you should have considered first; a unit that appears to have only L/R analog inputs and no digital inputs whatever is unsuitable for someone who has four sources to connect digitally.
Be that as it may, the Pioneer unit that you link has 3 optical and 2 coaxial inputs for digital sources, and if that matches up with the outputs on your source devices, it'll be suitable for your use. I'll also mention the Onkyo 504, which has 3 optical and 1 coaxial input.
The 120Hz comes about since Shawn draws the implication from the receiver being rated only down to 120Hz(which is unusual)that the crossover between the speakers and the sub may also be at 120Hz. That may or may not be the the case, but receivers such as the Pioneer and Onkyo do have 120Hz as one of the available crossover choices.
