I think ARC makes some great sounding gear but in your case, I don't see why you wouldn't get great results going with the C2300. McIntosh usually picks dealers that give excellent customer service. Your dealer may be willing to lend you one of their units, or even bring one to your home and set it up for you.
If for some reason you don't like the C2300, you may want to look at an Aesthetix Calipso. Its within your budget, sounds great and is built extremely well. I have one and am very happy with it.
