Doing the Power Cord Thing


Hey everyone,

So as you all know, I'm a DIY kind of guy when it comes to cables and speakers. I'll be building a new power cable using affordable parts from Parts Connexion and DH Labs:

and

They'll look nice, at least! :)


Testing will occur on the very last, new, Luxman 507ux in the United States.Will I hear anything at all? Or will this be just a wasted hour and wasted $100 assembling a cable?

Hi @lak 
I had to go look, I never took it out of the box. It comes with a standard looking 14 gauge, 2 pin cable. That's a little interesting, meaning the unit is double insulated, and does not legally require a ground, and therefore, no ground loops!

I will be using a 3 pin to 3 pin set up. The Luxman won't connect the ground, but since this is a shielded cable that benefit will still apply.
@erik_squires, thanks for the information. I guess I should also ask what power cord are you currently using before to make the DIY power cord?
Hi @Jim204 !
Thanks. To be honest, I am not a big believer in the extremes people here will go to in order to get clean power, especially with power cords.


I know the cable will be pretty, but I have no expectation at all it will improve things.

On the other hand, I do have all sorts of video, network and USB cables in my entertainment center, so I can see the shielding reducing the EMI/RFI.
Hi @lak
I posted the parts I am using, including the cord, in my first post. It's DH Labs shielded, 14 gauge, and 6' (2 meters) worth of it.  Total parts cost is around $100. Pretty close to what DH labs sells off the shelf, finished cables of the same type.

All I can tell you about the current cord is that it is black.  :D


Best,

Happy to announce that the tools arrived on time today, and I was able to assemble the components. Installing a power cord is never just installing a power cord. You find all sorts of other things to fix up while you go along. In this case I re-routed the cable, making an optimal L shape between my Furman Elite conditioner and integrated. I found the USB cable which connects all of my music to the DAC was intertwined with power and network and signal cables, so this gave me the chance to clean that all up.


I'm not sure I hear anything, but if I do, I would say, enhanced tube like liquidity and delicacy for flutes and violins, darker deeper sound stage and faster energy when needed.


Am I making it up? Was the benefit actually from the power cord and not from re-routing the cables? I'm not sure I am glad I got to work on a project again though. :) For about $100 it's a pretty good deal.


I will say the cable construction is really nice. The outer jacket is super resilient and flexible. Clearly very protective and capable of taking a serious beating. The three main conductors are padded with what feels like cotton yarn. The male connector was tight, and the female slid in as if oiled.
