Different Tubes and general purpose?

I’m trying to get a better midrange push or clarity out of my Line Magnetic 501ia tube amp.   Can someone help me understand what the specific function each type of tube performs in a power amp?  

I would like to upgrade several or all of my “stock” tubes but would like to understand where to start to beat enhance each aspect of the sound spectrum.   On my 501ia i have 4x KT120 and i believe those are power tubes, but please help clarify if wrong.  There are 2x 6SN7EH 1x 12AU7 and 2x 12AX7 (but the AU7 and AX7 look interchangeable to me).   As i look to upgrade where to i look to start, and why?  
Thanks in advance for help.

Once again millercarbon is wrong. I wouldnt call attention to this if it werent for his hubris and his constant Synergistic Research schilling. 

I am a fan of power conditioners only if you have power which is problematic. Further, I have never tried a power conditioner that didnt take me one step forward and one step back. I am more a fan of reducing noise using a passive device or a good isolation transformer.
