Help selecting a power cord.


All my gear has the factory supplied power cords  I’m ready to try 1 aftermarket power cable as a test.  So what brand power cable should it be and what device gets it first?  Tube pre?  Tube main?  D/A?  CD transport?  Roon Nucleus?  Subs?  GE Trefs?? Turntable? Oppo 103?   Which piece of my gear should be most affected by the improved power cord??  I look forward to the responses and will likely choose the cord that has the most recommendations.

Unfortunately, the Audiobacon cable review as all other suggestions is only an opinion which many will disagree with.

One has to begin somewhere. One can research the opinions of others or not-- utilize them or not. If one knows what one's priorities are, in terms of SQ, then reviews can be helpful as a starting point.  I never claimed others' opinions were a magic bullet. I would've thought that was self-evident!  

Unless, of course, you've discovered a purely objective means of determining how a given cable will sound in my system, in my room, to my ears/brain. . . 
Guys,

Just like @ Lalitk recommended; you would be hard pressed to find a better sounding/constructed PC compared to the Zavfino Majestic MKII at its ridiculous low asking price and ALL OCC Copper... You could not even build a DIY PC with ALL OCC Copper at that price and the Zavfino sports some fantastic technologies built into their cables.

The newer AQ power cords are quite good. Blizzard is a good value and sonics for the money spent without going overboard. For front-end gear, a PS Audio P-12 regenerator would be a great addition to your system.
