I have a pair myself. They aren't my main speakers but I do like them because they are a bit more forgiving than the speakers in my main system. A couple of things you have to be careful of with the Cub's is gain and how clean the components upstream are. You can get a lot of hissing/noise if you don't match your components right due to the fact that they are so sensitive. The Ayre is the best choice of the 3 you list. Its as clean and quiet as they come. The fact that it doesn't use an active line stage is a big plus. The ARC probably won't work very well for you. I would only consider it if you are able to try it in your system first. I have heard the Pathos, but I'm not sure. I don't know it as well as the other 2.
In case you are wondering, I use a VAC 30/30 on mine and I also took one of the Ayre V-5's out of my main system and tried it as well. They are both a great match. I do prefer the VAC, but its pretty close.
