Amp Internal Wire

In the case of tube circuits a centimeter or two of wire is in series with the conductors in the tube sockets and the pins up through their connections to the internal tube parts such as the plate not made of silver, the grid wires, and the cathode. These less than exotic signal paths are not considered an issue and they do little harm to the sound. The difference between more exotic less disruptive wires between tube socket terminals and other circuit elements makes the value of exotic wiring insignificant. In the case of resistors or capacitors or transformers which have their own wires connected to tube socket terminals you can't unroll a capacitor and replace the wires and re-roll the capacitor. You have to trust the capacitor manufacturer to choose the best wire. I think Mundorf can be trusted to use the best wire in their capacitors. 

For transistors you have wires of the transistors you can connect directly to adjacent components. Otherwise, where you can replace wires, there might be no noticeable difference but for a foot of pure silver wire without insulation and ease of soldering is affordable and will not do any harm. 

Ralph, I didn't understand that statement. Are you talking about frequency of mechanical vibration, and what aspect is the comparison about?

Not vibration- dielectric constant, which affects the quality of the capacitor that is formed between the wire and anything else its around (stray capacitance).

So wiring everything with silver is not necessarily but Teflon insulator  over copper is ok.

Teflon does not seal the wire. So you can expect copper in Teflon to be corroded. Add a bit of heat to the mix and the corrosion happens faster. So if using uninsulated copper, Teflon should be avoided.

Theories are nice.....but the only way to know what something does audibly....is to listen. 

All wires sound different.....all strandings sound different, all insulation sounds different, all wires (single strand or multistarnd) are directional (will sound different each way used).   The vibrations in wires seriously effect sound. Getting wires off the floor or away from most things opens up the sound.  If you cryo a wire it will sound different.  YOU HAVE TO LISTEN.  I have been listening to wires since the 70s......There is still no "perfect" wire......pretty darn good these days tho.....several of the suggested above are very, very good.

I spoke to Richard Vandersteen about this .....he says he uses wires, binding posts, et al after evaluating its performance at its place in the component.   He doesn't care about thick or thin cable, etc.   Look at the Vandersteen binding post...its much smaller, using small spades than any speaker I know of because of the sound.

Well gentlemen, job complete.

What can I say, but wow. It sounds beautiful, it sounds like silver - and a good implementation of silver - crisp airy highs, spatial, separation, and a thick low frequency bass - just exactly the kind of accurate sound I was looking for. I would absolutely recommend the overpriced Mundorf SilverGold wire..

Some photos of the job:

The 4B-ST has some quirks, but generally easy to work on, I'm listening while typing, just finished screwing down the top.

To those who say cable doesn't have an impact, it is just incorrect - plain and simple, this job/mod/upgrade was a NET WIN!

Thumbs up, I've really appreciated everyone's great inputs to my thread and my project! It was a WIN.
