This is a note to share my journey on DC power cables, as usual, these are findings based on my system and my subjective listening impressions, so YMMV.
When I first look into improving DC power cables was when I read a short write up from JS about how inductance can have a large effect on DC power cables, where a starquad cable like Canare 4S6 can help in reducing inductance. This is when I started my DC power cable improvement journey.
After replacing just about all my DC cables to Canare 4S6 and enjoyed the result for a while, I started to learn about the JSSG treatment, I got busy again converting all my Canare cables, and the result is a good notch forward in SQ.
Just when I thought things are settled in this area, big write up about improvements from JSSG360 treatment took my interest again. Not wanting to pass up chances to improve my system, I ordered more cables and connectors to make more DC cables. Once again, these new cables pushed my system up another notch. While I enjoyed the result, I also put together a quick DIY write up in case anyone likes to roll up their sleeve.
This round of DC cable heat wave lasted a while and related news got quiet until an AS friend talked to me about using thick 16AWG solid silver wires as DC power cable can have an even greater improvements, while that was an interesting idea, due to all my available time was consumed in other system improvement activities, I didn’t move this project up in my system improvement priorities until I placed the cables he loaned me into my system. Not only the WOW factor was quite profound, a couple weeks later, another outstanding review on Farad power supply also has the same impression I got on these silver DC cables.
This is when I decided to work on getting a few of these silver DC cables for my system. While Audio Sensibility has the Signature Silver DC Cable I like to have, but based on the previous experience, I know I also want to add JSSG360 treatment to these cables, meanwhile, the recent learning from different configurations in using Lush^2 USB cables, I decided to experiment by adding a third layer of shield to make it JSSG360^3 and see how that will work.
After two weeks of getting all the needed materials, I built 3 cables in JSSG360 configuration, two for my NUC and one for sCLK-OCX10. The cables replaced are Farad standard, Level1, Level2, and my self made Gotham cable in JSSG360 configuration. Right from the start without much of burn-in, the impression is very amazing. The ability of detail retrieval, dynamic, overall clarity and sound stage all move up a good notch. After about 10 days of burn-in, the already impressive SQ smooth out nicely, making the musical enjoyment even better.
After having a good baseline from JSSG360 setup, I added that third layer shield as planned originally to the first cable powering the NUC, the process was fairly straightforward and quick, once the power turned back on, it didn’t take much time for me to realize this experiment is a success. All the nice features from JSSG360 were all there, but the layering is much more defined, sound stage is even better connected together as a whole, bass notes are more extended and fast, and music feels richer than ever. Needless to say, I was a happy camper late into the night playing different tracks. Next day, I did the same thing to the second power cable for the NUC, and again, another positive step forward. Finally, on the third day, the last cable has the JSSG360^3 treatment, and now I am thinking which other cables I need to make plans to convert to these.
Things I learned from this journey thus far:
DC power is very important in audiophile equipment
Better DC power cable can make already good power supply better
JSSG360 treatment can help improve overall background darkness, which will help reveal more details, improve dynamic and overall presentation
Thick gauge silver wire perform better than equivalent copper wire
Thick gauge silver wire in JSSG360 is quite amazing
Thick gauge silver wire in JSSG360^3 is the DC wire to beat for my setup
