How to build a better DC cable

[nounours18200]

Hi,

 

I read from time to time that a DC cable can be optimized.

 

Do you know how to improve a DC cable (I mean how to build a better DC cable), used between a LPS and the device itself ? see attached photo.

 

Thank you

Al any well designed component needs is a reasonable DC input, no special cable required. All the heavy lifting is done in the component's internal DC supply.

The heavier gauge the better; shorter the better. Beyond that, the world of specialized wire is your oyster.

Thank you charlesphoto: I have just replaced the stock swtched P.S. by an AMB Sigma 11 Low noise Linear P.S. that I had in stock.

The DC cable is about 50cm made of OFC cable. I could make it shorter: 20cm is enough...

I will lesson tomorrow to see if I hear an improvement.

 

I should receive a major piece of equipment late of April, and I will continue to improve the setup of my LAN.

Meantime I  will remove every SMPS on the LAN, including the Internet Box P.S.

For doing this I have to manage to output 2A from another Sigma 11 that I have in stock: this requires better heatsinks....

The SMPS stock adapter provided with my Internet box is rated 2A, I don't know if it really needs 2A but it is not easy to check, so I have to design the heasink as if 2A are required...

I use a Ghent 16ga Neotech solid dc cable between my Sonore supply and microRendu, though I have DIY'd a 12ga in the past. Gives it a bigger beefier sound imo, though the 12ga was difficult to work with and  no way to fit it into dc connectors without leaving them exposed.
