What was the first power cable that you noticed a difference in the sound?

My first "contact" with the power cord issue was buying a high power Classe amp, 25 years ago, and one of the first things in the manual was the suggestion I should purchase an upgrade power cord...I was quite angry seeing this...bought an A/C Mater Coupler a few years later, and it did sound better...and the Classe included cord was a quality cord, not a throw away...sold the A/C coupler 10 years later, for the original used price I had paid...

This is my claim to power cord fame!

One of the reasons I eliminated the power cords from my mono amps was to eliminate two electrical connection points, the wall plug and power cord male plug. Also, another reason is to remove the question about what power cords sounded best. Running each mono amp directly to it’s dedicated electrical circuit sounds better, in my opinion, then running them with power cords and wall plugs. The rest of my equipment uses 12 AWG 1 foot long power cords. As far as all power cords go I would say keep them short as possible and 14 AWG or lower. FWIW, All four of my dedicated audio lines consist of Galvanized Steel MC Metal Clad Cable 10 AWG in wall wiring. 😎

@ditusa Sounds interesting.  The best PC is no PC.  So did you open up the amp cases and hard-wire directly from the wall box to the amp internally, or did you skip the wall box completely and run a continuous cable from you main panel directly into each amp?  Soldered connections?  And why did you choose to use Metal Clad cable within the walls.  I can't find anything that suggests a benefit to using MC cable inside residential walls.  I'm building a new dedicated listening room in the spring and am open to any ideas that can be incorporated at the time of construction.   Cheers.

I skipped the wall box completely. I ran the wires directly from the electrical panel and drilling a hole through the floor, ran it up to the back of each amp. Then I terminated each wire with a female IEC plug (WATTGATE 320I IEC 15A AC Power Connector Plug Standard BLACK) and plugged it directly in to the IEC connector in back of each amp...no soldering required no opening up the amp case. Hope that helps!

I have had a couple of power cords that I did not like on anything I put them on, now I just use sort of the most modern up to date cord I can afford on everything. Tho I did recently use some speaker cable that made an instant notable improvement with my little Harbie 3.0’s. From Pinetree.
