Golden Ears and Definitive Technology were both cofounded by Sandy Gross, and certain ideas have cross cross pollinated, or so to speak.
As for the term "home theater speaker" references used, I do agree its a poor term as it doesn't convey the intent properly. I also don't believe its bass that is being discussed, but instead an eager treble. There is always a difference of opinion in that part as our hearing varies more so in treble response than almost any other in the audible band.
Early GE models had some enthusiasm in the upper registers which meant pairings and setup would be key. The most recent Triton Reference is much better in this regard. An evolution in design they continue to make rather quickly. That is why I do feel that past listening is no longer representative of current offerings and should be revisited.
