Duelund DCA16GA

I've been thinking of combining two sets of DCA16GA for a 10GA run. Has anyone done this? If so, what was the result. I'm using a single run of DCA16GA now. My speakers only have one pair of posts, so I won't be biwiring.

Just received enough Duelund 12ga to make a pair of speaker cables with 8 single runs to each speaker, or a cross-connected quad to each of the two bi-wire binding post pairs on each speaker - 6 awg per +/- pole per speaker, or 9 awg to each mf/hf post and 9 awg to each lf post - can't wait to hear them

I recently had Parts Connexion make a 1M phono cable for me out of the Duelund wire and Duelund gold RCAs, w/ 1877 DIN. This replaces my Discovery Plus 4.

I was hoping for a slight improvement.. to my surprise, I was greeted with a much wider center stage, more open soundstage, richer textures and a richer tonality. Bang for the buck? That's with no break-in.

Just finished making a pair of  bi-wire speaker cables from the Duelund 12ga wire.  I have a cross-connected star quad going to the LF and HF of each speaker (8 wires per speaker or 6 awg per pole).  Getting the four 12ga wires attached to a single connector was a bear.  I tried soldering them but quickly learned that a solder pot would be necessary because the four 12 awg wires twisted together were too thick to solder using an iron or gun.
Fortunately, I had a couple of pairs of Furez SP8 SB60NP Bare Copper Spade Speaker Connectors that take up to 4 awg sized wire (the four 12ga wires were equivalent to 6 awg) and attach using two set screws.  I used Furutech's FP-201 G High Performance Spades at the speaker ends, which also connect using two set screws.  They have been  burning in on the Cable Cooker for a day so I will report back as to how they sound next week.
In the meantime, I am getting some very good sounds using another of my DIY speaker cables made from braided high quality copper wire in cotton sleeving.

Anyone compared the DCA16GA vs the DUELUND-72387 1.0 as speaker cables? Also are there any DIY links to make speakers cables out of these wires?
