A little observation on bass:
This appears to be a unique US phenomenon that good bass is almost always equated to "tight" or "super-duper tight" (aka overdampened) bass.
While we can observe overdampened bass in real life in recording studios, or at venues where the instruments (mainly drums) overload the room acoustics.
The exact opposite is the overly loose bass: just like what you get in a concert hall when you sit at the end of the row close to the exit. Still, it's realistic, but I have not heard of many people standing in line for those seats & that experience....
Yet, while listening to bass at venues with good acoustics at good places, bass is not overly tight - it's just right. A good SET can deliver that, the bass that has a good likeness of both texture in the bass and the right tightness. Overly tight bass representations bleed out the texture of the bass.
Push-pull implementations have bass tighter, with bland bass texture. (=More apparent power, less refined skill/technique.)
Single ended implementations have bass looser, with better bass texture.
Good implementations of each have less issues, and get closer to a fine balance.
It's up to your preferences from which side you want to approach bass - is tightness or texture your #1 goal?
