Which of these power cords ?

Hi cdc2,

I don't mean to rain on your parade but that leaves you $142.00 for each cord. Go to

It's a great online audio website, he did a fantastic review and compared 27 (I think) different power cords and gave his opinion of all of them. There were some great budget cords but even the budget cords were in the $250.00 - $500.00 price range. At $142.00 each, I think you would be wasting your money if you bought all 7 of them at the same time. Just my opinion. The way I would do it is buy 2 or 3 of them  to start with and put them on the most important pieces such as your sources whether that's the cd player or the dac or the streamer. Then as you save up enough money for the next round you can put them on your preamp or integrated amp. A good power cord can make a nice difference but at the $150.00 price point there's not a lot of good ones to choose from. Eventually it will make a big improvement in your whole system. Good luck with whatever you choose.

I can't believe manufacturers would all compromise the sound of their components by using inadequate power cords?
I can not believe that expensive power cords make an audible difference. At my rural home the current runs about 750 feet through aluminum cable from the last transformer to my service panel then another fifty or sixty feet through copper Romex cable from the service panel to the wall outlets for the stereo. A six foot power cord is at most .75 per cent of the total cable supplying power to the stereo. How can six feet of expensive power cord correct problems created the other 99.25 per cent of wire. I just don't buy it. That being said I am careful to use good quality power cords , usually the cords supplied by the manufacturer of the equipment.

" I can’t believe manufacturers would all compromise the sound of their components by using inadequate power cords?"

They are not in the business of power cords and better cords mean higher costs as most components have price point goals. Manufacturers will let the end user decide as there are hundreds of options.

Your second paragraph is a tired argument and has been hashed out in this and many other forums.

Not to mention manufacturers are usually the last to find out about these things. 

@Kingharold It's the same theory as all those high fidelity speakers having the right true sound but they all sound different.
