I know this is an old thread, but just read it.
Firstly, may I say I love the PS Audio cables. However, the Transcendent is NOT a silver cable, it is OCC Copper. The Reference is silver. I own both and both are great.
Before I make my next comment, may I point out that I do believe that cables make a difference, in that the better cables take less away from the signal.
With that being said, cables do not add anything to a signal, or if they do, this is distortion and they are not a good cable. The distortion will always be a loss of something in the signal, not a boosting of an aspect of the signal. So, a so called bright cable is simply a cable that is revealing all the high end and less of the low end, so should actually be termed a dull cable. It is not adding brightness, it is cutting the low end.
If you have a bright sounding system, ie with too much high end, then a cable that distorts the signal by cutting some high end may result in an improvement in the sound, but I would say this is the wrong way to be getting the sound you are after.
The PS Audio cables (Reference and Transcendent) seem to be an honest, revealing cable and will show you where you need to improve the other components in your system.
I remember those Siltechs, that also came up in my research when I was looking into other silver ICs.
