Quick power cord question:

Mr. rodman99999

Thanks for the info over the Audioquest "DBS system: Noise-Trapping DBS Packs".

I see that it is a BS sleeve that Audioquest claims it will work on any cable: Interconnect, and speaker..." interconnect (analog or digital) or speaker cable ".

The nature of those 3 is very different, especially of the line resistance to ground. This is a product that simulates the best snake oil over a cable, but it’s a solid with a battery and a LED.

They also lost me on this: https://www.audioquest.com/accessories/audio-enhancements/preamp-jumpers
As directional on an AC signal is the greatest BS ever!
To remind everyone, that Audio is an AC (sine wave) that flowers both directions, each 50% of the time. So, on which 50% is that benefit the signal and on which 50% it damages it.

Would you please be kind to ask Audioquest (a known cable maker for decades), what speaker cable do I need, if I use an Amp. with DF=400, and cable length is 3m?

Dang!, And I just lost my "Opinionater 5000" measurement device. The one that came inside the (Ballistic popcorn vault and Anechoic chamber" 
. "It fell of the back of the truck 'round that one turn".

My ribs hurt soooo much right now...

It was Mr. rodman99999 post I ref. to.
Sorry, I have no idea.
I think it will have a 3-4 digits price tag.
Save it.
You can flush down the drain the same amount, it will give you the same feelling.
