Do Kimber KCAG's sound bright????


I have Kimber KCAG through out all my connections except for Transparent Audio speaker cables and PS audio power cables. My system sounds a little bright. Have Bryston amp and Adcom preamp. Is copper all round better???? Mike

It's a complete misnomer that pure silver wire is bright. I run Kimber KCAG from my phono pre to main pre. I also run Siltec MC4-80 (pure Silver) to my power amps. They are neutral and very revealing...not bright. If they were, I'm sure my Wilson Watt/Puppies would tell me so. YMMV
Further I would add that I also use pure silver speaker cables (Siltech LS-180). I feel that those who experience the tonal balance turning bright when using silver cables in their system are experiencing impedance resistence issues related to differing cables and or components.
As a cable manufacturer, My experience tells me that cable geometry is a bigger determinant of perceived brightness, which is a way of agreeing with you Rockitman, but with different words.

However, copper and silver have different characteristic sounds with copper adding a thickness to the upper bass and lower mids, which tends to make the sound warmer but muddier than silver. If you design a cable that sounds balanced with copper, and substitute silver, the muddy accentuation of mid-low frequencies goes away and the silver introduces it own resonant problems in the lower treble. The resulting cable may sound too lean and bright.

The challenges for a cable designer are therefore quite different when using copper than when using silver, and a reasonably balanced result is possible with both of them.

My company never uses copper as copper cannot achieve as low a noise floor as silver or gold. What we do find is that there are several ways of combining different metals (in our case silver, gold and platinum) that can significantly diminish the characteristic sounds of the individual metals. Many others still get excellent results by just using geometry to balance out the characteristic sound of the metals. It is all in the implementation, and judging cables by the metal used is mostly meaningless.
