POWER QUESTIONS for my integrated home theatre/2 channel CJ ET3 SE set up

First time posterI have two 15 amp outlets behind my tv. Both outlets are relatively new and about 6 feet apart.
In OUTLET 1:
I have a PS AUDIO POWERPLAY IPC 9000 (10 outlets 2x5) with the 5 pieces plugged in :

• 1. NAD M25 7 channel amp

• 2. CJ ET3 SE -

• 3. Marantz AV8801. PP -

• 4. Oppo 205. -

• 5. JL Fathom Sub -

In OUTLET 2 :
I have a Furman powerstrip with:Pannie Plasma TV
and 5 gaming consoles.
I recently added the CJ ET3 SE as I love 2 channel audio. I am utilizing the home theater function with the CJ and having noise/sound problems with the CJ. It isn’t all the time but sometimes there is hissing and humming other times. I changed the tube in the CJ twice. I didn’t know that the CJ is extremely sensitive to all types of interference. Interconnects are 3 and 4.5 feet. It seems when I do the theatre bybass function the interference develops.

I am doing 7.1 analog from Oppo to Marantz/CJ theater bypass for movies in analog. Oppo to CJ for 2 channel music.
Questions:
1. Should I have the CJ plugged into the 2nd outlet of OUTLET 1 by itself on its own conditioner or do something else.
2. Is there too much on my PS IPC 9000 ? Maybe put the NAD M25 on its own since it is a beast?
3. What is the best recommended power cord for the CJ? i know this is subjective but was curious.
This is my first tube amp.  I appreciate any input THANKS!
