No direct experience, although I do have a FiiO THX AAA amp module that I use daily. Take this with a grain of salt, but I think over the years (well beyond even my time here) I have learned how to read impressions and reviews well, and I have a fair amount of experience. All of that suggests to me that the Empyreans and this amp would probably be a really good combination. But that is just an educated guess, be curious to hear from somebody who has tried the combination. I would really love to try the Empyreans and perhaps when I complete this degree I will treat myself.
