Replacing internal wiring.

I have done this on my Spica's and on my JBL L-166's, and yes, it does help a little bit.. a little smoother, a little less hash-y. I would NOT recommend replacing wire in an amp unless the amp's designer is consulted or it's a mod others have done repeatedly with successful improvement. Also I just finished working with some silver solder and some large 10 gauge mult-strand solid core copper wire and I had to use a 100 watt iron and it really had to heat up the wire before that silver solder would melt! good luck.

Xiekitchen, what kind of silver solder ? Some of it won't melt or bond for ANYTHING. I use an 800* tip and some silver based solders still won't "grab" very well on some metals.

I have re-wired amps, preamps, speakers, etc... Sometimes, the results are subtle, sometimes they are staggering. One thing is for certain. You should document EVERYTHING ( which wire goes where, what direction, etc... ) before even attempting to remove anything. This will allow you to go back to where you first started on the whole thing or replace just one part. Keep in mind that all of the wiring and connections will take a bit of use to fully settle in, so don't go off the deep end right away if you're not thrilled. Sean

The idea is OK, but the length of the wire inside the amplifier and speaker is generally much shorter than that of the speaker cables, and so I would expect that it is less critical to have such high quality wire inside the amp and speakers. It should make a difference, but I would expect the difference to be much less marked than upgrading the speaker cable itself. These reasons have always put me off doing any such mods.

Sean, i recently re-wired a pair of mono-blocks. In the process, i was able to re-route the wiring for a MUCH shorter and cleaner path. As i've said before, if some of the EE's designing audio gear were doing RF gear, we'd still be using tin cans and string. Some of the stuff that they do just doesn't make sense, especially when talking about NON "mass-produced" hand built stuff.

Putting all of the various "snippets" together end to end, i was able to take out almost 4 foot of wire out of each amp. This probably gave me at least another 100 wpc due to the reduction of series resistance*. Sean

You'd get less skin effect too, Sean.
