Let's talk about Silver...

@ghdprentice I can verify that less expensive silver cables are generally not great. I have a box full of cables that I bought for $100 to $200 hoping to get lucky.  I'm not using any of them.  The Apature cables are actually pretty decent, though.

I opened my wallet and bought the Black Cat Silverstar 88 cables and they're excellent.

I just purchased a used XLR cable to try out between my dac and preamp. It took about 5 minutes to decide that it's going in the box. 

The Graham Slee CuSat50 is one of the few less expensive cables that really impressed me ($175 used). It's all copper. It's unfortunate that they don't appear to be available in the States for people to try.  I ordered a second pair on ebay from a UK seller. 

About 15 years ago, I tried a high quality pair of pure silver interconnects in my audio system, but they actually were too bright for my taste.  Currently, I use a super phenomenal pair of top copper interconnect made by Audioquest (Thunderbird XLR).  I honestly believe that the Audioquest Thunderbird interconnects are my end-game interconnects.  My speaker cables (Superconductor 3), and one of my power cables (Aluminata)  are made of  Alumiloy (JPS Labs).  Then, I also utilize one Audioquest silver/copper power cables (Firebird) for may DAC.  My other two power cables, and my ethernet cables are all made of copper.  I'm extremely pleased with the sound quality that the mix of audio cables produce in my audio system!!!  Happy listening.               

Of course cable choice is both personal taste and system defendant.  My main cable, a 4-meter run from my linestage to my amp is Audio Note Sogon (pure silver litz).  My speaker wire is Sogon as well.  I am considering Sogon or some cheaper Audio Note wiring for the internal wiring of my speaker.  The alternative is some really old Western Electric wire.  

Biggest effect will be in simple tube equipment like Audio Note.

I liked it for headphone cables but not used it in speaker systems
