Speltz Anti-cable needs break-in period?

Break-in time is about 60 hours for these cables. Paul needs to try out the 10 GA. wire it sounds a little better and he also needs to change from red to a white wire because the white wire sounds better, the color of the wire has an affect on the sound. I heard about the affects on cables over here http://www.belt.demon.co.uk

The white wire sounds lighter and more open at first. But after a while, especially if you move it around often, the sound becomes smudged, even dirty.

Jon Risch talks about cable jacket colour to some extent on his website. While i don't know if this is actually audible at audio frequencies, i do know that some manufacturers have played with such things at radio frequencies.

In an independent study conducted by a reputable College, identical copper wound heliwhip antennas were made. These heliwhips were then impregnated with fiberglass for rigidity and corrosive purposes. Four different colour dyes were used in the fiberglass: white, orange, black and grey.

When tested, the grey antennas always performed better for some reason. Don't know if the grey dye had better conductivity or less thermal loss, but that's what the tests showed. Never got to see any further results, so i don't know if they were able to find out the reason behind the variations in performance.

As far as twisting vs untwisted, the further that one spaces the cables apart, the more high frequency roll-off will occur. This can tend to soften the treble response of a bright system and / or seem to fill out a somewhat lean sounding system. Twisting the cables will increase the high frequency response of the system by widening the bandwidth of the cabling. This occurs due to reduced inductance.

As far as break-in goes, moving a cable can not only cause stress cracks in the crystal structure of the wire, but may also cause differences in conductivity at the point of termination. This could be either within the connector itself ( wire bonds to connector ) or where the connectors mate externally ( male RCA to female RCA, etc... ).

It is not uncommon for cables to sound slightly different after moving them. After a period of extended signal flow, the sound of the system typically returns to what one was used to. That is, unless the cables were relocated into a different area where they may be exposed to a different ( more OR less ) RFI, EMI, etc... Sean

Sean,

If they used pigments in the fiberglass that are similar to those used in coatings (I suspect they would be very similar as the pigments are cheap commodities & would have the same function in fiberglass...color & hiding the substrate) then there may be some explanation as carbon-black is used in grey toned to black pigmenting. White pigment would typically be titanium dioxide...years ago it was "white lead" = lead oxide that is the root of the pre-mid seventies "lead paint" issue.

Actually the Anti-Cable website basically seems to suggest what Sean says: that twisting the runs may ameliorate top end roll-off by lowering total inductance. I was apparently misremembering when I implied that Speltz's site suggests twisting will do the same for bass response.

I tried researching further on the web, to locate whatever reference I was remembering about twisting, inductance and bass response, but couldn't find it again. I did, however, find seemingly contradictory claims surrounding this topic -- and that was looking mostly at independent technical writings and those posted on manufacturer's websites, not those of non-technical audiophiles (such as myself) in forums such as this. (There seems to be similar disagreement over the importance of characteristic impedance.)

So it's hard to know what to make of this. I guess the best thing to do is listen and compare, twisted vs. untwisted. The one time I tried separate-lead speaker cables, I twisted them together as recommended by that manufacturer (the cables sounded rolled-off in the treble and bass-heavy, so I didn't buy them, but I also didn't try them untwisted to compare). A lot of the online papers I read were written by technophiles whose larger agenda was often that fancy audiophile cabling is snakeoil and a ripoff, and who also claim inaudibility for different variables which I personally believe I have heard. Whereas of course the manufacturer sites are mainly trying to sell a product.

As the for the effect of dielectric pigment, given the arguments presented above, why should gray 'sound better' than black? Or red 'sound worse' than clear or white? In any case, it seems to me that the whole point of the dielectric in Anti-Cables is that it's as minimal as possible, in which case so should be the 'audibility' of its pigment.
