Any cheap silver cables for Talon Khorus?

Try TG Audio. I too don't know what your definition of cheap is. I'm curious, though, about why you want to go cheap with Khoruses. And also why the cables have to be silver. No need to answer these questions. I just think there are more important factors involved in cables than whether they're silver or not.

I'm the Van Den Hul fan since they give you a possibility to get unterminated wire that you can use as a realy great cable.
If you visit their website wwww.vandenhul.com you will find a huge chart of wires or just by simply calling them you will get their best and cheapest advise how to build your own speaker cable with their best quality parts and materials saving a huge buck.

I also recommend trying out the cables from Homegrown Audio. I was very impressed at how much I enjoyed their Super Silver interconnects at only about US$90/meter.

Their speaker cables are also pretty impressive at about $25/foot.

I would also highly recommend that you try the silver cables from Luminous Audio (not LAT). The synchestra speaker cable is also about $25/foot, and it's transparancy and balance in my system were just unbelievable.
