cheapest cable upgrade ever

Trying to wrap my head around this.

For speaker wire, the red, +positive side from amp to the speaker would have the positive end toward the speaker and -neg toward the amp..

For the negative side terminal (same speaker) wire, is the + pos side oriented toward the speaker as well or is the - neg side toward the speaker and the +pos toward the amp? Can you post a speaker wire picture?

I like cheap.

I'm dubious of the effect but I agree with those who defend the suggestion.  Look, it's one thing to make sure noobs don't spend their money buying a $750 dongle that won't do anything, but these DIY tweaks are what the hobby is about - it's not snake oil if effectively free.

That said, I'd like a cogent scientific explanation...

Dear all, on RCA, digital and ethernet: batteries close to the signal target with battery ‘-‘ to the source. On speakers: close to the speaker withsignal side with ‘-‘ to the amp, return with ‘-‘ to the speaker

pedroeb,

It looks like mine is going in the opposite direction, that is, the positive pointing in the direction of the signal flow. It seems like that should be the correct way.

my mid-fi has daily battles with stray electrons in my electrical system and these little buggers like to backfeed low voltage thru my Amazon USB cable that carries signa lfrom my MacBook Pro to my SU8 DAC, so I wasn't expecting much. I started by strapping on a battery, maybe dead I didn't check-  near the USB end that goes into my Re-Clocker on the SU8 DAC. hmmmm.... it does sound a bit more defined and separated... found another battery and velcro-ed that missing link to the speaker end of an XLR...hmmm.... by the way do these batteries have to be charged? ima gonna follow up on this...
