Ah, I get it now. So, you want an "improvement" in your cables. What exact aspects of sound reproduction are you looking to improve upon versus your current cables? If you can't answer this specifically, I think you may be putting the cart before the horse.
IMO you shouldn't even be contemplating wires or whether Rotel electronics are compatible with B&W 802s (a complete mismatch BTW). If Magnolia is your current frame of reference you haven't even scratched the surface of awesome sound, and you really need to get out and hear other systems. As I mentioned earlier, search out and visit other true high-end dealers in your area (you definitely have some around there), even if that means driving an hour or so. That will start to give you a better perspective of what you like and what you're missing, and then you can identify what your next logical step should be. I'm on the other coast and have no idea where your good dealers are, but as I mentioned earlier I'm pretty sure Silverline Audio is in your area and at the very least you should go there and hear what Alan has set up. I'm confident that it would be a very valuable experience and one I certainly wish I could take advantage of.
Sorry to be preachy here, but I'm really just trying to save you some time and money.
