Yes, cables do make a difference -- regardless of price...

I thought you may find this interesting…or not.  I know, another "cable post".  Disclaimer up front — I am a believer that cables can make a difference in the sound that you hear from your system.  With my speakers, like most high(er) efficiency speakers, I can hear large and small changes made to the system components — and cables are part of that system.

What I want to share is an exercise that I went through with my better half in setting up her recording equipment that she will be using to record audio books.  The hardware part of the system is simple:  Audio Technica Cardioid Condenser Microphone AT2035 connected with a XLR cable to the Focusrite Scarlett 2i2 preamp.

We started with the XLR cable that came with the microphone and recorded the short introduction of the book she has been contracted to record.  Then she recorded the same section using each of the our XLR cables I have on hand:  Vovox Excelsus, Mogami 2549, Gotham GAC-3, and Grimm TPR. Each of the cables have the same Neutrik connector and are very good studio cables that I have used in my system at one time.

Listening through headphones via the Scarlett 2i2, it was super easy to hear distinct differences in these cables.  The differences were not small and very apparent.  In the end, the Mogami cable was the winner — it seemed more open and warmer than the other cables and suited the tone of her voice the best. I have heard similar differences from these cables in my stereo system but not to the significant degree borne out by this exercise. 

To keep going, today I replaced the $10 USB C to C cable that I bought as an “upgrade” from the Scarlett 2i2 to a MacBook Air with a $70 Audioquest Forest cable. We were more than surprised that with the AQ cable in the system the drop of the noise floor was very significant and the blackness of background made the sound even more crystal clear.

The purpose of this post is not to promote or compares cables, just a public service posting for those of you who do not believe cables make a difference.  They really do affect how your system sounds (positive or negative) and if you cannot hear a difference then maybe looking at the transparency of your system is a place you should examine.

Imagine peace everyone.

Re: mains connection 

Poorly designed components (or components that didn’t look at this issue) can have leads that act as TRANSMITTING  antennas of noise.

Given the rats nests of interconnects and power leads in the back, I wouldn’t be surprised, at all, if an interconnection doesn’t pick up garbage transmitted back out from an unshielded power cable, especially if they are touching and follow parallel for a fair length.

My theory is based on a sample of one, where the power cord of my turntable laid flat against my phono cable and I could (and anyone could) hear a hiss until the two were pulled apart.  Kept happening due to how everything was smashed together in my original set up.

Went away when I switched to an Amazon (nothing fancy, but definitely shielded, you can’t detect current with a “live wire” detector) mains cable.

Mind you, the phono cable is the thinnest interconnect and the MC signal the weakest signal in the chain.  So the most vulnerable.

When I redesigned my rig, it made me run all interconnects XLR (including phono), picked fully balanced components (including phono amp) and took great care lay out wiring with a considerable air gap and no touching.

it’s also super sharp looking behind the scenes which makes my OCD very pleased. LOL.

Not fancy wiring, either.  Mogami platinum with high end furutech ends.  Speaker wire is larger gauge pure silver from a military aircraft (used for fire reasons), braided by my daughter.  I doubt all in its $1000.

I think we are talking the same point, or close.  I'm certainly not going to spend thousands on a main.  But $40 (probably was $20, but Washington DC has been printing money for some time now) on a shielded power code is good insurance when dealing with cramped wiring at the component end.

My long runs (to right sub and two to phono preamp), btw, are nice, medical grade, cables stolen from a broken MRI machine.  Other than really nice plugs, heavy gauge, and length they are not particularly exotic.  I suppose they have no ferrous alloy of any kind, but I'm not sure that's relevant. I just ran them along the wall in typical Home Depot wire routing "tubes" to keep them neat and untangled.
