Silver Wire

dragu- I realize I misread your question a bit, but maybe i lucked out by still answering a related question. sorry.  i'll revise a bit ...

If I was doing what you're doing, i wouldn't care if it's copper or silver. I'd go with the wire that has the best of the electrical properties mentioned above. That would include the quality of the soldering. Also, if it was me i'd try to keep the gauge the same or bigger (if not too cumbersome) and if possible go with a wire geometry that might lower inductance significantly while keeping capacitance within reason.

First, you need to know how to remove solder and resolder well enough to proceed.

I won't answer your question directly, because mine will be just another opinion. I will say you can't disregard the quality of the wire you're replacing. You want to be very careful not to replace wire with worse electrical properties than what you replace (e.g. resistance, capacitance and inductance). I'd strongly suggest you measure each wire you remove for all these properties and not replace them with anything that has worse values of these properties. What is worse? That might be a separate thread. We'll see.

Maybe I'm not following you, but it seems you've replaced 18 gauge with "doubled-up twisted runs" of 16 gauge wire and you noticed a difference. It seems you've proven that this lower resistance and likely lower inductance has improved the sound of your speakers. Why would you think it's because of the Silver?

Understood. You are providing good info for the OP to use and decide on his own. Always worthwhile to do so in my opinion. But I think there needs to be a bit more detail wrt the 12 gauge experiment, in particular the size and shape of the wire and quality of the connection. You did write " I wasn't too thrilled about using the disconnects" but you didn't explain. Not a big deal, but the OP should know quite a bit more before putting that information to use. My opinion.

Anyhow, good posts. I am also considering re-wiring everything I can if I think inductance in particular can be lowered significantly in any of my runs (inside or out of components). But let's be clear on something ... it wasn't my logic being stated in my post. Though I'd love to take credit for it, I believe Misters Faraday, Oersted, Ampere and Henry (to name a few) were a little more influential toward that end.
