What do you LIKE BEST about your current audio system?

From the bottom up...
Hard driving deep tuneful bass
Layers of inner detail,clear with rich timbre
Expansive sound stage, highs not bright yet completely expressive. 
The way it looks and feels and the emotional reaction I have when listening to some damn good music.

Too bad it doesn't always sound like I posted above but I working on it.... 
Some body real please tell me about power conditioning , I am an un believer.
