cheapest cable upgrade ever

Ok I tried this crazy tweak on my less revealing second system placing the batteries “-“ to source on my AQ Carbon USB cable feeding my DAC.  Hard to wrap my head around another illogical tweak but this made a significant improvement.  Adding a pair of batteries at both ends improved it even more.  Bass improved, more clarity, fuller sound stage?  My Carbon cable is smelling like coffee now!  

Is it just my brain messing with me?  Even if it’s a placebo effect I’ll take it. Hard to explain but its working and those batteries aren’t going anywhere.  I will try it on my main system to see if any improvement can be had.  I’m wondering if your system is extremely revealing already if improvements are not noticed.   

Glad I gave it a try....cheapest cable upgrade for sure.

@antigrunge2  thanks for sharing sounds fun will give it a go!

This is what I feel this hobby is all about.  Experimenting with different products/tweaks makes for more sustainable enjoyment.  I especially like cheap diy ideas but will spend moderate $’s for significant gain.   Buying new components gets you in the right game but the fun is getting the most out of them especially on the cheap.   Using some of these tweaks has gotten mind bending improvements out of my systems I didn’t think possible while saving thousands on component upgrade chasing.    Not all are winners but my big winners have been: diy ground boxes for speakers and select components, fmc- optical cable- fmc between router and streamer, fuses from QSA and China made fuses filled with graphene/quartz crystals, AQ jitterbug on usb, diy VH audio power cables, 12TC speaker wire chinese copy of Kimber Kable, nobsound springs on speakers/ components,  Nos ‘50-60’s ebay tubes,  Nps 1260 3d contact enhancer, diy helmholtz resonator bottle array and diy argent room lens.

Fun stuff no matter what the naysayers throw out.  Noticeable SQ improvement that builds along the journey.

@mrskeptic Could be trolling...you will only know if you give it a try.  Many don’t but some are shocking successes.  

@antigrunge2  Thank you for sharing this suggestion.  Ok mind blown again…I tried this tweak on my main system and got similar results that I got on my second system prior.  Better bass, clarity and definition.  

Placed battery pairs on the following:

Ethernet cable from router to FMC (2 batteries)

Ethernet cable from FMC feeding my Bricasti M5 network streamer  (2 batteries)

USB cable from M5 to my DAC (2 batteries)

Speaker wires both + and - (8 batteries)

Interconnects from DAC to amp (4 batteries)

Not really able to determine which batteries make the most impact 

but the sum of all batteries definitely improves the SQ.  All batteries are staying in place.  Crazy simple inexpensive tweak…much appreciated!

All of my batteries have the - facing the source flowing from - to + for my digital and interconnect cables and they sound great!  On my speaker the batteries + is facing the + post on speaker and - battery facing - post.  (My batteries are as close to source plug end as possible and close to the speaker posts).  Significant improvement for my systems.

@tweakmenow Glad you had an open mind to try it and it made an improvement.  So simple and cheap.  Interesting how it affects some systems and not others.  I did a blind test just to verify it was legit and confirmed these batteries were making a SQ improvement. Cheers!
