Looking for really fine cables at really low price

Glad you like the power cables. I still love mine also. 

Dual (i.e., double run bi-wired) twisted pairs of thee WE 10awg here for speaker cables and a quad version (i.e., 4 twisted WE 10awg wires for pos and neutral, plus 2 more for ground - 6 wires total) for power cords to my Class A monoblocks.  Really like the sound.  In the process of making some twisted pair shielded power cords from the WE 10awg for front-end digital gear.

Have also tried versions of using the WE 16awg and WE 14awg for speaker cables.

I still believe the 16awg wire probably sounds great with low to moderate powered amps as used by Jeff Day and others but IMO it is hard to beat the larger 10awg for big solid state amps.

The sound of the Duelund wire on higher powered amplifiers may further improve if configured as a twisted four-wire star-quad providing 13awg per pole.  Even better bi-wiing with two quads per speaker.

Has anyone tried braiding 8 or more of the 16awg wire as done by Kimber or Jena?

I have image not. 

Strange as the WE10 gauge is the polar opposite of sizzle and sibilance in my rig. Smooth highs and tons of body. I don't terminate mine however. Just bare wire best.
