I find this an interesting thread to follow. Over the past several months I've put together a full loom of the Lavricable Grand 5N silver interconnects, speaker cables, and power cords. I'm wondering how the interconnects that you are talking about would compare.
Xangsane SP-9001AG silver interconnect
So, encouraged by friends I've bought some bulk Xangsane SP-9001AG silver cable.
The cables has two squarish/flat solid core silver conductors (purity supposed to be 4N), one silver plated copper drain wire, teflon, cotton, copper foil, and finally silver plated copper mesh.
Jacket says OCC.
Well, it's been playing in my system since a couple of days, burn-in is far from being over, but I can already tell this is a very very good cable, with great tonality, fantastic transparency, dynamics, taut and strong bass... this is the best cable I've heardin my system (by hundreds of miles), and according to some friends you need to go very, very high in price to find a better silver cable.
