That is axacly how I have run here for 10 years at least.
Brick wall, amp to wall.

No power conditioning here - everything straight to wall.  I’ve found the more I reduce extra doo-dads in my system, the better it sounds.  Stock power cords, good quality, but reasonable cost interconnects and speaker cables, no special networking equipment or Ethernet cables, and no more isolation products. Sometimes simpler really is better.

I tried multiple ... Uberbuss, Blue Circle, PS Audio. Gave them all up as I had too much $ invested for too little, if any benefit. These days I use Zero Surge but my 2 channel system is effectively off grid with Vinnie Rossi and Uptone equipment anyway.

For a few years I used a PS Audio Power Plant Premier.  It made a slight difference with my cheaper equipment but didn't do a thing for my expensive gear.  When the PPP died I didn't notice a huge change.  It was not worth having it repaired.   Now days, I live "Off Grid" on Solar/Battery power.

I have been running most of my systems without conditioners for a couple years. I was using a Furman unit for a long time. I bought a Niagara 5000 and was not impressed with it over the Furman. I tried against the wall at the same time and found the Furman was not really helping either. So now I run straight to wall.

That said, I got an AQ Hurricane power cord at that same time and it made a very audible difference and is in active use.

I do use an AQ big powerstrip, but not with the belief it helps sound a ton.

We use a Shunyata Everest as our power conditioner. We also have two whole house surge protectors - one supplied by electric company and another called “Leviton 51120-1 120/240 Volt Panel Protector.”

We’ve had the latter in two homes and it works great for us. Of course we had it installed by a licensed electrician.

I am questioning the need for power conditioning.  Switching power supplys are getting good.  I have moved to passive power conditioning using Less Loss Firewall 640x.  It seems to do a decent job at reducing noise in the system.  Wondering if anyone else has experience with these units.
