Power cord choice?

I’ve tried many power cables from $ to $$$$. It is not only system dependent but also dependent on which component it’s used on. Therefore be sure you can try or preferably compare several at same time before final sale. Interesting effect I’ve come across is ‘ground path’ plays big role with power cables check out stealth brand cables to learn about/understand it although they are out of price range. A dark or bright cable could be exposing noise in your system to investigate. I found Greatest power related benefit using equitech balanced power standalone unit. Undid my 4 separate dedicated lines in favor of balanced unit. If you go that route wait on cable purchase because it changes things. Btw Subs and computer/hardrives are big noise producer on ac lines to other components. Obtained huge benefit with furutech top line connectors opposed to same cable without them.  On lower price end try vh audio airlsine great for price and for very basic budget but good quality try signal cable brand in ny. Upgrade a/c outlet in wall porter port ac outlet inexpensive furutech also good but more expensive option. My preferred order to proceed
1 wall outlet
2 balanced power
3 cables - biggest improvement preamp then  music server then dac 
Hopefully saved you some time and $$
Happy Listening

Power cords often cross other cables.  The radiated noise can affect the audio in those cables.  Look for a shielded power cord from Mouser or Digikey.  Don’t get the biggest cable as large gauge wire is cumbersome.  16 gauge is normally sufficient.

If you can find a used Audioquest Thunder, that would be my pick.  I never believed in power cords other than having at least a proper gauge to provide enough current until I tried the Audioquest Storm series.  I too couldn't believe that a power cord could make any difference.   I was wrong.  My experience with the AQ cords is that they lower noise.  I would have been very happy not to drop $$$ on power cords but the right ones can make a difference.  Also, if you are using a power conditioner like a PS Auido P20 or similar using something like the AQ Storm Series cords between your conditioner and equipment is a real plus.  The very low impedance of a well engineered power cord with reduce compression of the sound stage in complex passages.  

Anticables power cords are audibly better in my systems. No doubt there are other manufacturers who make good power cords but I think they are exceptional. They have an easy trial policy that makes trying one a no risk proposition. I was quite sceptical before about power cords (and regenerators) - no longer.

Once again, sales pitches from commissioned people are influencing buying choices.  I think the best person to consider for this advice is the designer of the product.  If he, or the bean counters, compromised on such a simple piece of wiring, you should buy a different product, rather than second guessing a compromised design by pouring more money into it.  If the power cord is not the best needed for the application of an expensive piece of equipment, the engineer/designer has wasted his time with the rest of the design, and more than likely also used other cheap parts inside the unit.  AS far as asking another audiophile, one must control for all possible differences, from the amps, speakers, sources, and of course the room acoustics.  But!  Keep trying.  I have always enjoyed watching people continue wasting time, as I am now doing, striving to adjust their psyches to try to gain approval, both from others and from their view of themselves, as they strive for perfections that continue retreat from us, maybe logrythmically, faster than we can learn that the idea of finding perfection is futile.  Just enjoy the music!  Don't worry about it.  If you hear something that sounds better, decide if it is for you.  Quit inventing problems to solve. There are only a few hosts who are worse than an audiophile who, rather than playing good music for his guests, obsesses over a few bars of music, while asking... well, no matter what he asks it is always, "Am I cool enough, yet?"
