HiDiamond Power cords...

Ozzy,
They look good but I have no experience with them and I have not tried the P4 yet. I also do a special mod to my P3 and some other power cords that greatly improves the sound.

Bacardi,
Liking the Power 3 has nothing to do with the price point for me. It has to do with the sonics. I did not crimp the wire because the ends of the Power 3 are soldered. The positive differences are much better sound stage, detail/definition, and tonal qualities/harmonics. I must add that I do my own mod to the cord/connection that improves the sonics even more. This is proprietary.

@Sabai, I absolutely agree with you about sonics. If I was to order the Oyaide M1/F1 male/female connectors could I change these myself without soldering and will I have a definite upgrade similar to what you described as better sound stage, detail/definition, and tonal qualities/harmonics. I really would like to experiment with that if its a no brainer to swap.

The Graphite plugs and IEC's I purchased will not replace what is on my HD Cables.
I plan on making a couple of DIY power cables using high quality silver/ copper wire.

Bacardi,
If you order the M1/F1 all you need to do is take the terminations off the Power 3 and replace them with the Oyaides. There is no soldering required. Just make sure you get the soldered ends tightly into the slots. You have to familiarize yourself with the Oyaide construction first. The aluminum casing screws on and off. And at the base there are 2 screws for stabilizing the cord in the housing. Then there are the two long screws that let you get inside the housing so you can loosen the inner screws to get the work done. Make sure you mark the ground so you don't get any connections mixed up.
