A most neutral and transparent power cord

The Zcable Gold Lightning is a really good sounding cord in your requested price range.

I am having great luck with a VH Audio (Chris Ven Haus) power cord on my Musical Fidelity A300 integrated amp.

Very neutral and balanced presentation.

Here is a link to my review of it.

It is also priced very reasonably (less than $100).

need to know what its for to give you a recommendation. one brands transparent is another brands noisey.

I second the VH Audio powercord. I just built 2 flavor 2 cords for my monoblocks and am favorably impressed with their performance. They have lowered the background noise below what I thought was possible-- I thought it was quiet before, and didn't realize how much noise was there until it was gone. Supplies to build 2 6 footers was $130 or so and it took me all of 30 minutes including beer swilling.

Try FMS "Nexus 63" and you won't be disappointing.
Best of all, that I tried before( Electraglide, Cardas, Audio Tekne etc.)

Good luck, Jack.
