Power supply AC cords: any reason to upgrade?


As it happens my system has three linear power supplies converting 120vAC to 5, 12 and 24vDC, and Rogue Audio Ares pre-amp with a detached-box power supply of its own. Is there any benefit to upgrading the line cords feeding these units, or can I just use the decent-quality plastic molded cords the manufacturers provide?

@john_g What do their power cords look like at the moment?
e.g. like the PC’s that are supplied with computers (i.e. skinny) or something more heavy duty?

What are the linear supplies like - good quality or el-cheapo?

Do you want Store bought or DIY?

Is the DC power cord from the supply of good quality or cheep and nasty?

Can you replace the power cord on the DC side of the power supply, or is it connected inside the case?

The drawback with units like this is that
1. unless you are a competent DIYer - it gets expensive real quick
2. they may not be worth the expense

Finally - How crazy do you want to get?

Generally - upgrading the PC’s on the small power supplies can provide better sound quality, but the cables you can purchase tend to be too large/expensive to make it a viable proposition.

DIY is more affordable

The power supply for your Ares looks as though it might benefit from an upgraded PC.

There are several good PC’s out there - Signal Cable Silver Resolution springs to mind, good but affordable.

I would recommend looking at the IC’s between the components and speaker cables

I highly recommend KLE Innovations product mainly because they work extremely well and compared to the competition they start off more reasonably priced

@john_g - since you are experience with DIY you could try the HELIX power cord detailed on my web site....

They may seem a little daunting at first but they are actually pretty easy to make and outperform most other PC’s I have tries (some up to $1500)

I would use the following
- a 16 gauge conductor for the hot conductor
- two 16 gauge conductors for the neutral
- a 16 gauge conductor for the ground

Keep the same quality of conductor as identified on the site from Take Five Audio - they are great quality

Using lighter conductors makes it much easier to wind the helix coils

My system currently uses a mix of 10 gauge for mains and power distribution and 13 gauge for source components and sounds amazing

I also have a mini system that uses a 16 gauge version and it is outstanding.

Let me know if you have any questions
