What Makes your System Special?

First system I've had that is virtually distortion free. Also first system I don't feel needs to be upgraded. I'd like another pair of Wireworld Eclipse (have 7s, would like to add 8s for bi-wiring). Maybe Eclipse Silver 8s if they make a difference in my system). Otherwise I'm done.
BTW, looking to replace my KEF 201 stand mounts with Klipsch Forte IVs (home theater system). 

The time i spend with my system makes it special, and being able to listen every single change i perform makes it more so.
What i would change, i cannot change the small room i have but i could experiment with some kind of room treatment like diffusers, resonators.

The ability to listen all day and into the night with absolutely no harsh treble, or teeth gritting ear searing painful treble. 
  Just smooth , smooth, smoooooooth.

zero fatigue at any volume. Great detailed and flawless midrange.
And, yes it’s all mine!!!

@lalitk That setup does look very special!

@akg_ca  I've heard those Harbeths and agree completely.
