I’m considering upgrading my speakers internal wiring

@bobbyloans i’ve gone down the rabbit hole of upgrades from every direction and if you are inspired to do any particular thing, I would certainly not stop you… However

A big upgrade that many people miss out on is simply addressing the AC power in your system. This avoids alteration of the equipment which you might sell someday anyway, and gives you some forever new equipment that will be much bigger than the wire in your speakers

In my opinion, and from thousands of hours experimenting ... the place to begin and best value in audio upgrades is a Shunyata Theta 2.25 m AC cable

Even one of these will change your system for the better

If you’d like to voice the system, a little brighter go 2,0 or 1.75m

if you’d like a little bit more on the low end, go with 3 m

if you have more than $1000 to spend, Shunyata research has many power distribution products which are all very effective and have no artifacts on the downside, which can't be said of the offerings from other companies in the power business.  Also, comparatively to the field, the Shunyata stuff is not only better. It's very reasonably priced.

and definitely ignore anyone who says that speaker wire or AC cable wire doesn’t matter, these well meaning people either haven’t done the work or they don’t have a system sufficiently resolving to hear what’s going on…

Every single thing matters it’s just a question of degree.

Hello, I upgraded the internal wiring on my Rogers LS3/5a speakers only because they were very thin small gauge wire. I think it’s only worth changing the wiring if you see it’s not good quality wiring installed.  

I replaced the original wire with 18 ga Neotech teflon wire. 

I’ve always questioned the validity of spending tens of thousands on cable interconnects for components, and I have asked this forum more or less the question you pose: if interconnect cable is so important, why aren’t the amps, preamps, and especially speakers similarly wired point to point? It’s meant not as a snark, but a straightforward question. I have never gotten not only a good answer, I have never gotten any answer. At all.

For my Altec 604Cs, I ditched the crossover that they came with, bought a pair of Mastering Lab crossovers that were designed for the 604Cs, and had someone replace all the capacitors with audio grade Jensen foil capacitors.

At a minimum, if applicable, I would do away with any crimp connections that could instead be soldered and replace the binding posts with low-mass pure copper. There is no way those mods could have negative consequences.

If you change the wiring using UPOCC with Teflon, or cotton, dielectric and stick with the same gauge as OEM, how could anything negative come of that?

I think where people may have had negative results would be by changing the wire gauge in the high frequency paths.
