I found a good review for anyone who's interested:

It looks like these retail for $879.95/pair in the 8 ft length. For example:

I believe it's possible to re-terminate these using AudioQuest 500 Series Banana:
$270 seems like a very fair price to me. Even if you end up re-terminating all six connectors on both cables (probably unnecessary), your total cost is only $659.90. Still a great value, IMHO.
Scott, can you provide photos of your actual cables? The photos I see in your original post from February 25th appear to have the silver-plated connectors, but you said yours have gold.
