Help selecting a power cord.

If you can’t instantly hear the difference in a blind test, then you shouldn’t buy it. Unless your system is at really high levels of performance and you are comparing expensive to very expensive power cords... it should be a no brainer. Most of us who have built great systems over many years remember their first digital cable, analog cable, and power cord upgrade moment... the moment we went “holy cow, how can a power cord make that much difference?”. If you don’t get that... just keep working on upgrading components.

Power conditioners are very dependent on your location not just on your system. In the UK we generally have good clean power and I live 4 houses away from a small electrical sub-station. Probably for this reason power conditioners make no improvement, and actually make the sound worse. In the US I believe that the quality of the power is poorer and many seem to get big improvements from conditioners. But it will still depend - rural locations vs city apartment blocks will have very different quality of electrical power. 

Re power cables - there are too many brands to know more than a handful but of the ones I have heard I can recommend Shunyata. The mid-series Alpha range by them are particularly good value.

Shunyata power conditioning for me. Also on the cords. But to get real results go with alpha NR or Sigma NR level.  Both not cheap but you will get noticeable results!

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?
