Copper v. Silver IC sound


I think most would agree that there is a trend for copper IC's to give a fuller midrange at the expense of some transparency, and for silver to give a pure extended top end while sounding a bit lean elsewhere. Some people will "mix" their IC's, say, using silver from source to preamp, then copper from preamp to amp. My question is: In this example, could one "lose" the warmer midrange in the first silver run, such that it could not be "recovered" in the second copper run? Conversely, could an initial copper run "reduce" the highest frequencies, such that they would not be "available" to the silver cable during the second run?
Or, are all the frequencies always carried along equally by most silver/copper IC's, with the final "presentation" of mids versus highs determined by the last cable in the system? Obviously I need to just try the experiment, but I don't have all the cables on hand, and I'd like to hear the experience and opinion of others. Thanks.

Silver is a better conductor than copper at any frequency. Radio Frequency (RF) cables of higher quality are typically silver plated copper when cost is not an object. Some antennas even make use of silver plating to increase their conductivity. They can get away with just plating the conductor as RF is ALL "skin effect" and travels on the surface of the conductor.

Audio frequency ( AF )cables may be either silver or silver plated. Obviously, the more silver used, the more expensive the cable SHOULD be. Since AF signals tend to ride both through the core of the conductor and on the surface ( skin ), you might run into some type of problem when using multiple types of materials within the same cable. My guess, based on a limited understanding of electron flow, is that a distortion may occur when a signal "crosses" between the top layer of silver plating and the core of the center wire which is copper. As such, i've seen others that are more "in the know" state that in order to minimize this problem, the silver plating must be applied relatively thick. I would assume that the evenness of plating may also come into play.

As to using silver IC's or speaker cables, can't pass judgment there. Never felt the need to use any. I would suggest that if you have an IC that seems bright or edgey, try letting it burn on a Mobie for a while. It can make a world of a difference in terms of smoothness, clarity and transparency. I would not have believed the difference if i had not experienced it myself. I had tried lesser cable burners with little to no difference being discernable results.

As to using copper to replace what was lost with silver or vice-versa, that is not possible. Adding to or removing from a signal is simply a distortion. You can, however, end up with additive or subtractive distortions that compliment each other. The end result is that it may present what is a pleasant sonic picture to you. Don't get me wrong as i'm not criticizing here, i'm simply saying that this is where system synergy and personal taste come into play. Sean

Jallen brings up a good point about the difference in the type of conductor used, not only the material used. I agree that stranded and solid sound QUITE different using identical geometries and dielectrics. Changing the gauge of conductors using identical geometries and dielectrics also changes the sound. Lighter gauges will sound quicker and leaner and vice-versa.

There are SO many variables that picking the "right" cables can be quite tough. That is how i got into building cables and doing comparisons. You can build cables to your own specs in terms of grade and materials, geometrical designs, lengths, etc... and see what factors contribute to the sonics that you are looking for.
