There are products on the market that replace crap quality wall warts with much better cables. Not worth the hassle of reinventing the wheel to save $40 bucks when you put a value on your time.
Simple and Effective Upgrade for Wall Wart Power Supplies
I recently purchased a new DAC that is powered by a 12V wall wart power supply. In trying to extract the best sound from the new DAC, I turned my attention to the power supply and power cord. Upgrading the power cables on my other pieces of equipment yielded great results, so why not try it with my DAC?
I looked into upgraded power supplies and was quickly overwhelmed by the number of options and reviews and I wasn’t really in the mood to drop more money on my source at this time. I reasoned that the little cable that runs from the power supply to the DAC could be improved on but it’s all one piece and I didn’t want to rip anything apart. I had a spare C7 connector power cable lying around and tried to figure out how to include it in the chain. I went on Amazon and purchased an adapter to go from a “female C7” connector (proper name: C8) to IEC connector. I bought another adaptor that went from “female IEC” (proper name: C14) to a NEMA electrical outlet style plug that I could plug the wall wart into. I hooked everything up, turned on the system, and let it warm up. I now had a high end power cable upstream of the wall wart, instead of directly plugging the wall wart into the wall outlet.
The first track I put on was “Bloodflood” by Alt-J. If I had to sum up the improvement in sound I heard from my improved power supply chain, that word would be: ridiculous! There was so much more slam to the music. Dynamics improved along with better instrument separation and a 3D soundstage became more apparent. Since I had a spare power cable laying around, the total cost for this upgrade was $11.16. I highly recommend you give this a try if you haven’t done so already.
Happy Listening!
