Ok The nice folks at Have Inc sent me a 1' sample of 1694a so I could see if it would be what I wanted. I want to use this for both speaker wire and interconnects. When I stripped the cable, the first thing I noticed was the construction: 16 gauge copper core Teflon insulator Aluminum 'foil' Aluminum weave Outer insulator Aluminum? Isn't aluminum rather... um... bad for high end audio applications? I was told that the 1694a was some of the most high end. Would I be better to try and find something with a copper weave also? I want to make some interconnects and speaker cable that will last me for a while so I'm willing to spend the extra money on high quality parts. Is 1694a (or some other with aluminum construction) the way to go? Thanks!
