Mind sharing where you got the cable from? So far the only low price pure silver cable I found is the Fiios cable but it doesn't come in 2pins flavor.
XINHS is the oem of some of these listed cable. Check this thread tons of great info on inexpensive cables. Might want start at the end it has a ton of responses.
