Yes, most people think that the XA.5 and INT-30A are the better sounding, more tube like amps from Pass.
You're pretty well into the diminishing returns area here so I don't think you'll find big differences between the amps, unless you have developed your critical listening skills.
The Pass is class A. if that is important to you, and it is to some people, that's the way to go. The CA200 is class A/B. It sounds very similar to the Pass to me, it uses less juice, it runs cooler and so can be left on with less concern about heat, which is the enemy of amps.
