I think Harbeth versus the Devores will lead down two significantly different paths to get best results. One is high efficiency, one is not. THat alone makes a huge difference regarding what might be needed for best results for a highly discerning listener.
Not all listeners are equally discerning. Those that are not have it easier and are not as hard to please.
If op has not heard many speakers/systems, I agree it would be desirable to get more mileage under his belt with various types and what to expect from each before deciding. Or, just pick one and focus on getting which ever choice it is set up and performing as best it can based on whats best for that kind of speaker. Its all good stuff, but apples and oranges from a pure technical perspective and what will go along with each in order to make shine.
