Interconnects/Cables of your choice, and why?

Kubala Sosna Realization (and Elation in my second system).

I also spent many hours comparing, and picked Audience AU24SX.  Loved the highs.  But when comparing the K-S Elation to these, much more full bodied with no loss of upper resolution.  FULL SPECTRUM smooth.  Revealing but  not glaring at all.  Meaty and sparkly.  All Copper.  Have to admit, now I just go with them, as in a new AES or USB cable etc.  Never disappointed and just not going back to all the trying and swapping again.  Of course now they have the new Ovation line...

Cerious Technologies, all 3 levels...I use them all...

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.
