Power amps into surge protector/Conditioner or DIRECT to wall? Final verdict?

Pretty expensive solution cleeds. I'm not sure why everyone thinks separate lines will reduce noise. The are all connected to the same main.
Any power supply worth is salt filters noise. It should be particularly good at filtering 60 Hz noise. You would get much more bang for the buck buying a more powerful amp than buying a line conditioner.  Put shorting plugs on the inputs of your amps and put your ear right up to the speaker. You hear any noise? I don't even with my preamp hooked up on a shorted input with the volume all the way up. No noise, none. Yes the phono preamp has some tube rush. Preamp on my usb input to which my computer is connected with the volume all the way up, no noise. All my front end goes to one surge protecting power strip. The amps have 20 amp dedicated lines but no power conditioner. No noise. People will say that I am just lucky and have clean power. Every modern system I have set up is powered the same way, no noise ( excluding phono amps). I also do not use analog preamps which is part of it for sure. Analog preamps will have at least a little noise. Does a little noise affect the sound quality. If it does us vinyl people are in for it. Is it all just a marketing scam aimed at gullible audiophiles?

@erik_squires  Thanks for your feedback Erik and all the clear & concise input you have contributed to this topic in the various threads over the last week. It has been helpful and very much appreciated.

@blindjim  Thanks for your empathy and encouragement in this confusing topic.

Panamax m 4300 ex, do the job for me + stones and crystals I added myself with great success...

The question is are the crystals working on the rf or the vibration.

They works on the 2, RF and vibrations, but I am not the physicist, you are Geoffkait...
