@ICUDoc .
I'm using the Sigma NR between the wall and the P12. I have 2 Alpha NRs, one to my 140 Pro from the P12 and the other to the Keces LPS which supplies my Roon Nucleus+ and the EtherREGEN. I think there's a benefit to having the power cable to a power conditioner being at least the same gauge as the heaviest gauge cable you have from the conditioner which is usually the cable you have to your amplifier. For a while I ran the system with one of the Alphas to the P12, the second to the 140 Pro, and a Shunyata Delta EF (no noise reduction filter) to the Keces. I had one of my stupid "what if…" moments one day and asked myself "what if I used an Alpha NR to the Keces?" so I swapped the Alpha feeding the P12 and the Delta feeding the Keces. I noticed that transients and loud passages didn't have quite the same impact which didn't surprise me but I thought everything else improved so I decided to get another Alpha NR but ended up with a Sigma NR instead. That's why I think that you shouldn't power a conditioner with a smaller gauge cable than the cable from the conditioner to your amp.
I got the P12 and cables from a local dealer, Brisbane HiFi.
Re your comment about having lost a bit of detail and transparency and gaining a bit of an electronic sound after moving your system to a new room, I'd suspect the cause to lie somewhere in your room acoustics and speaker/listening position setup. If nothing in the system has changed, then the change in sound could well be attributable to the change in room. I'd start looking at the differences between the old and new room, things such as more or less soft furnishings/carpets/etc, more or less exposed glass in windows/doors and/or hard reflective surfaces, speakers closer to or further from walls, listening position and the surfaces near it and so on to see whether you can find anything which might cause the change in sound and try and remedy that. It may not just be the nature of the difference, whether you have more or less of something, in the new room but also whether or not the difference is nearer to or further from the speakers and/or listening position. Also consider any asymmetries in the setup such as windows on one side of the room and not the other and so on. If your room has an open archway entrance, also consider what's outside the room. My room is carpeted but there are 2 archway entrances and the floors outside the room are ceramic tiled. I dealt with a touch of brightness by putting a woollen rug on the floor just outside each entrance. If you have open entrances into the room, things outside the room can also affect the sound you get because some of the sound leaving the room is likely to be reflected back into it from surfaces outside the room.
Another possibility for the change in sound is that the power point in the new room is on a different circuit to the power point in your previous room and the new circuit is noisier than the old one.
