Duelund internal speaker wire?

I rewired my Lowther speakers with Dueland wire a couple (maybe 3) years ago and it was a nice improvement in SQ. 

It´s Duelund and not Dueland.

..just as an aside....I spoke to Richard Vandersteen about this very thing.  He said that they extensively use many different wire to make their speakers sound the best...sometimes wire with non"audiophile" credentials are better for a specific application. As an example....their speaker connections are small and non"audiophile", but have been proven to sound the best.....just sayin'

I have owned Duelund rich nice but not the most detailed . much better is the VH Audio 8 conductor 
small solid core awg21 of Occ Copper 6-9s and foamed Thin Teflon dielectric ,litz Wire.a bit of a bitch to unravel the Litz  to seperate the wire  leads,natural cotton centercore , veryvery clean detail  and open a awg12 gauge I highly recommend get away from Brass  connectors outof your system speaker terminals ,wires,and  equipment, goldover Copper Smuch better, more natural.
this wire is roughly $31 a foot about $360 for 6ft pr then connectors ,the Oyaide Gold Copper Spades are only $60
thesebeat cables well over $1500-2k ittook about4-5 hrs to make them . Runin time 4-500 hours. 

I know this is not the same as changing internal wiring,bu
