I would say yes, these speakers sound great and I still enjoy sitting down and listening every chance I get. But that is just me, and everything you have asked about is subjective. I don't have any kit to give you graphs on response, but subjectively they are the best thing I have ever heard. I will temper that by saying I haven't heard many of the speakers in the world - especially at the very high end so its entirely possible if I went in to a botique I would realize that these sound like crap. But I doubt it. As much as I love the speakers I guess I would hate for you to invest in the parts and time and then go "man that imjatse guy on the internet is a ******, I hate these".
