Interconnects/Cables of your choice, and why?

I'm in the process of trying thigs out to upgrade my balanced interconnects right now. Been using a lovely set of Stereovox 600s for many years, it's time for something new.

I just got a Wireworld Gold Eclipse 8 ad also their Platinum Eclipse 8. I also plan to try the Veritas Argentum X and possibly the Tubulus Concentus v2. We'll see which one I end up keeping.

I also go with Transparent in my main system for speaker cables and IC’s. However for power cords I have a mix of Shunyata and DH Labs-which I have come to really appreciate more and more. I also use DH Labs IC’s in my second system (couldn’t afford Transparent throughout for a 2nd system because I wouldn’t want anything less than Super line). 

Townshend F-1 Fractal IC's, digital cables.... As good as Transparent but at 1/10th the price. If you're gonna use Toslink, make sure they're glass Toslink and not plastic. 

I may be mistaken, but I suspect the OP was referring to interconnect cable typology and not brands.

I use Cardas best clear beyond for interconnects ,and Cardas Clear  for loudspeaker  cables it is very detailed yet still very natural ,the clear for Loudspeaker cables it is slightly warmer then neutral. Great synergy and balance .

for Ethernet  Sablon and Tubulius Ethernet cables, USB  Stealths  New. 
variable adjustable  cable it brings a nice balance , power  cords Cardas,

and Audioquest  Thunder  to Hurricane.
