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.
