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.

Probably the best advice I’ve taken from Agon. Period.

Maybe this British built conditioner makes power stateside more like UK AC, well with half the voltage mate?

I’ve found that even the base Shunyata Venom V14 power cord makes a noticeable improvement over stock power cords on a DAC. I think the benefit comes from better shielding of electromagnetic interference. That could be a good starting point.

FWIW, not every "audiophile" power cord sounds good. I’ve heard power cords that made my system sound worse than with the stock power cord. Matching the characteristics of a power cord with the characteristics of your components is important to do. The Shunyata Venom seems more neutral in its effect on all equipment.

A good way to then test out more expensive power cord at low cost is to use The Cable Co's lending library of cables to see if you can hear any improvement over a Shunyata Venom.
Paul Speltz Anticables PC did it for me.  Being a disbeliever for many years I finally tried a pair (with a full refund guarantee).  One in my DAC and one in my amp.  The improvement was immediate and very obvious.  I was shocked at the benefits.  I've tried many others since, many of them much more expensive but keep going back the the very reasonably priced Anticables. 
Start on your power amp and for $200 or less try the IsoTek EVO3 Premier....Flexible, easy to use PC. Your music should sound more real...a violin sounds more like a violin....piano sounds more like a piano...etc....Could follow this up with an IsoTek or AudioQuest power conditioner.
