…and we audiophiles interested in their use as I2S cables generally want to stay away from the eARC versions, correct?
From earlier in this thread…
I just don’t want @Gareth (or others) to inadvertently order the “wrong” cable model.

Correct. You want the 48 models not eArc. Dragon 48, Firebird 48, Thunderbird 48 etc…
You have probably seen it many times on this thread but if you haven’t call Nick Lucini at TMR to get the best price!
Here is his direct number. 720-441-6172 or email at

Correct !!
2muchgear has summed this topic up vey well.
thanks one of the few times it looks like we are on par with the US price wise
take care

Have you tried JSSG360 shielding on dc cables or interconnects yet? That could be a fun rabbit hole
@flowcharts ,
Yes I have 6 of them powering everything in my digital chain. The streamer SGC i5 , my netgear modem switch, UltraRendu, matrix, and direct to the DS board. I bought the two meter length Ghent Gotham JSSG360. I replaced each one one at a time. They all offered a noise floor improvement over the stock LPS cords I had. You have to upgrade AC power cords too to the LPS and you get another step up boost. It all matters significantly in the streaming chain. Even placing sorbaothane under the footers sized for equipment weight gives you lower noise floor.
I did find cable elevators do nothing for the Gotham cables and they are not affected by other power cables running parallel. But I tried to space them apart.

Sorry, I should’ve clarified - I meant the actual process of applying the shielding (two floating shields around the cable, connected only to each other at each end). I got the idea from also getting the excellent ghent gotham dc cabbles, and seeing your foil wrapped madness. I’m at a bit of a standstill on dc cable purchasing until I decide whether to go hypsos, plixir, farad, jcat or something else, so I applied a form of jssg360 with copper foil to a stock hdplex cable just now as an experiment
The stock hdplex dc cables are otherwise unshielded, and sound like, to use the technical term, doo-doo. Low hopes for this experiment, but hopefully there will be at least a little improvement powering my jcat usb card.
I haven’t tried foul wrap on DC cables having bought the Gotham jSSG360. The stock HDPLEX 300 are not the best
I bought some more copper tape and going to do doble layer drain shields for my cheaper LPS power cables having found they were best for modding amp and DAC AC cables. The JSSG360 double floating works for DC and signal cables per info I found. I would be curious of your success.
Maybe you could try this wire too?
The best way for the shielding to work properly is a separate wire connected to each end of the shield. This is sufficient for shielding from DC to very high frequencies. Note the shield does NOT have to be connected an earth ground, the “ground” of the circuit at either end, or any thing else for that matter. A cable with a shield the is not connected to anything else except itself (ie a separate wire from one end to the other of the shield) will be highly effective in shielding what is inside.
Where does this wire need to go? It can be either inside or outside the shield, but if it is inside it can couple to the signal wires inside, so it is usually best to have it outside the shield. Note it has to be insulated from the shield except for the ends where it connects to the shield. It should intersect as little of the external field as possible so it should NOT be tightly spiraled around the cable. Just running along side the shield is best, although a very loose spiral (say one turn per foot) is almost as good.
I have a roll of copper foil tape and have been following the comments on using the tape on power cords. I’ve been trying to visualize what’s been done and not sure if the outer insulation is being stripped off or if the copper tape is being applied over the outter surface of the cord. Tried finding some visuals on it online but they all seem to be over the conductors. Are there any visuals you could point me to?
Thanks in advance.
I take a layer of heavy duty tin foil cut in half to 6 inch width length of braid and over lapping male connector end. roll it around cord around cord semi loose so it doesn’t tear. Needs to be continuous piece.
Next take 3 inch copper tape with conductive adhesive cut long enough to go entire length of cord. Then wrap around sticking to Al foil so it overlaps and covers and sticks to foil. At male end of connector barrel pick up the ground plug enough so RF drains to ground at male end.
Amazon carries copper emi tape 12.99 a roll. Tin foil must be heavy duty get at grocery store. The double layer makes for better shield and easy to demod if you wish to sell the cord some day you have no adhesive to clean except at male connector.
Note: power strip in photos is for LED light bar separate from dedicated audio circuits.

Thank you, that seems clear. The copper tape I have is only about 1/2" wide so that wouldn’t work, I guess.
You find that it reduces noise (RFI/EMI) without rolling off the treble – you wouldn’t do it otherwise.
It is just as @dchang05 described. It will also remove muffled sound in mids, solidifying bass, take nasty noise out of highs, let’s you see deeper in the soundstage. It doesn’t roll off highs only cleans them up. I have only done Diamond and Diamond Xtreme Core Power cords

Thanks again for both the method and the description of the improvements and to @dchang05 as well. If I were to try this it’d most likely be on a Acrolink 6N P4030 cord which I believe is unshielded. I have others of the same type and connectors (Oyaide P-/C-046) that I could then compare.

“V”, my man. Ya gotta photoshop out that power strip in your photos. These pictures really undermine all of the street cred you have earned here on the forum.

The power strip is for LED lights that is separate from my dedicated 20 Amp line. No audio or digital chain plugged into the Belkin strip

Perception, V. It’s all about perception. You can spin this anyway you want, but once folks see those power strips in your posts, the facts no longer matter.
You have been warned.
Have a great week. I am off to test the roads here in East Tennessee. Two inches of snow from late yesterday afternoon and overnight equals an extreme weather event here in West Knoxville.
Wish me luck.
