Power cords or power conditioner

I’m at a cross roads and I’m looking for some advice from those have have gone down this road. I recently added a 2 channel integrated amplifier to improve my 2 channel performance. I had been using my Datasat LS-10 for music and while it sounded really nice, it was missing the depth and clarity that I know my speakers are capable of. My speakers are KEF Reference 3s, rest of my 2 channel set is is as follows:

Luxman L 509x

Luxman D-03x

Roon Nucleus Plus

Lumin U2 Mini

Transparent Audio Super speaker cables

Nordorst Red Dawn XLR, Blue Heaven USB

Wire World Platinum USB

All power cables are DYI using Oyaide Tsunami V2 cable

So what I feel I am missing is that 3D holographic sound stage. It was there with the Luxman 509 when I demo’d it, but I am unable to get that experience at my house. I feel that majority of equipment is up to the task but I am curious if I should ad a top shelf power condtioner like a Shunyata Triton or Torus AVR20 into the system or replace my Intergrated’s power cord with a Shunyata Alpha NC? I’m getting tapped out, so for now it can only be one or the other.

Or should I skip the above and focus on room treatments?
