Any new tweaks out there?

I know we've had threads dealing with this topic but newer members may have experiences not presented thus far. For instance, I'm sure many of us have noticed the the skimpy 12-14awg leads on the power supply of our amps. Has anyone tried replacing them with say, 8awg just to see what happens? Or changing out main caps? Or changing to pure silver signal wire? Or using the solder provision instead of the hold-down nuts on binding posts on the amp-side? Or going from E-I to toroid, etc.....? It would be great to hear about something new.

Geoff. Why don't you like brass?

Why don’t I like brass? I have ranked cone materials according to their relative Sound vs. Hardness. Generally speaking, the *harder* the material the better the sound. But it’s a little more complex since cone shape also affects the sound. Brass is actually a relatively *soft* material, relative to steel or ceramics, for example, which I think is why brass, generally speaking, doesn’t sound as good in terms of openness and tone and dynamics as high carbon steel and NASA grade ceramics. The same logic applies to carbon fiber cones.

Umm, @csontos, putting 8awg power cord on an amplifier that’s being fed from a 15 amp circuit with 14awg Romex or a 20 amp circuit fed with 12awg Romex will do you no good at all. Look up Ohm’s Law, and you will see that the weakest link in electrical power delivery to your amplifier limits everything else.

I replaced the short 4" 12awg leads to the 2 main caps in an Ampzilla. Bottom end was faster with more impact. Those big caps need a hi way. Hence the large thick buss bars you usually see them hooked up with.
