HiFi vs Cheaper Power Conditioners; What's the difference?

Can you define sound better?  The system I’m putting together (my first system) is:
processor: marantz sr6013
 (connected to furman via audioquest nrg-z3)
front speaker amp: mcintosh mc202
 (connected to marantz via audioquest red river;
  furman via audioquest nrg-z3;
  b&w cm9 s2 via audioquest rocket 33)
center channel amp: mcintosh mc7100 mk 2 (bridged)
 (connected to marantz via audioquest red river;
  furman via audioquest nrg-z3;
  b&w center 2 s2 via audioquest rocket 33)
turntable: clearaudio concept
 cartridge: blue point special evo III
phono amp: ps audio nuwave phono converter/pro-ject ds2 tube box
 (connected both to furman via audioquest nrg-z3)
power conditioner: furman 15 pfi
 (connected to wall via audioquest thunder)
"screen: si solo pro 100"" slate 1.2"
projector:  epson ls1000
( connected to wall via audioquest y-3 and furman pst-8)
front speakers: b&w cm9 s2
center channel: b&w center 2 s2
rear speakers: b&w fpm-5
side speakers: b&w m-1
sub: jl e112
 (connected to wall via nrg-y3)
 
other accessories: alexa input
  apple tv 4k
   (connected to furman via audioquest nrg-y3;
    marantz via audioquest cinnamon)
  logitech harmony elite

The main questions I had were I was thinking of getting another furman 15 pf i to connect the e112 into and also if I need a second power conditioner (perhaps a ps audio p5) to plug both the mcintosh amps into.  I have a bunch of separate wall outlets but don’t know if they’re on the same circuit.  Wall outlets are 15 amp.  Any help greatly appreciated.

Oh and getting a mrcu lda for clearaudio concept which z3 will hook into.  If I get the pro-ject will have to do the same w it unless I get the rs (but not much point since no xlr on 6013).
