Welcome aboard aKnyght 
What cables are these?
They are tinned with solder or copper?
They keep flexibe after the tinned process?
thanks for the warm welcome!
i am using speaker and interconnect cables from
alp-tone audiothey have two series of cables that use conductor wire made of tin-plated copper. each strand of copper has a very thin plating of tin which is applied during manufacturing. this type wire was common back in the early days of hi-fi with Western Electric being the most prominent manufacturer with their ks-13385 audio transmission wire. several years ago, tinned-copper wire became very popular among audiophiles in japan. lead by jeff day, this has now spread to a small but growing community in the US. i am using their alp.wE series cables which have conductor wire manufactured by the new Western Electric to their original specifications and they have provided a huge improvement in the sound of my system.
these cables are quite flexible, more so than others due to the multi-fillament sheath they use.
if interested, there is more info on the alp-tone website and on jeff day's blog: jeff's place.
