Bought Kimber Kable 8TC bulk cable from Aliexpress to make speaker cables for my surround sound second system. Looks identical, the copper strands vary in gauge and are wrapped in Teflon same KK. Very happy with the sound improvement for $38.00 (5m)
I do like to make my own power cables following VH Audio’s Flavor 4 DIY recipe. Chris has some nice wire for reasonable prices.
