Changing internal cabling, anyone use Jantzen solid conductor?


I have a pair of Mirage M1 speakers and I'm replacing the internal cabling. The existing cables, I can see, are oxidized and over 20 years old. Cable technology has come a ways since then. So I decided to go ahead and replace them.  I saw these jantzen cables, wonder if anyone has used them and what's the result.

Years ago I used dh labs t14 for internal cabling and it was detailed and fast and I liked it. But I need around 45 feet. And dh labs has gone up in price since I used it years ago. So I'm looking for a more cost effective method which will still lend excellent results, assuming there is such a cable.

Again thanks to all who respond to my posts your information has been sincerely appreciated.

Get the new Duelund 16ga stranded and thinned wire in cotton for $10 meter from Parts Connextion. Duelund as has a new 20ga for $7 meter I think. They are just wonderful.
Here is the part number, yes under hookup wire and sold as a single strand. Simply twist every 1.5 - 2 inches and mark one positive and negative with heat shrink on the very ends. Do not terminate, just use the bare wire. Bested my $2000 cables and others have had the same experience,.
