Speaker Cables for my Focal Sopra 2's

Wireworld reduces presence a little in exchange for enhanced imaging.

You may use what Bryston does use: Belden, or Van Damme. 12awg.
I would go with a higher gauge like the 5t00up... it is a real 10awg (measured without insulation), and is less than 50pF/ft capacitance, less than 20uH/ft inductance, and resistance is less than 1% of the lowest impedance point that your speakers will ever reach.
In other words, it is like no cable at all in the eyes of your amp and speakers.
Bryston was keen on canare lv61s and 77s, as they used to package it with their names on it.  They seem to have moved to van damme from the UK.
If you contact focal and bryston, they will confirm (unless they are partnering with a cable marketer at a trade show)..

I’m using Supra 3.4s right now, between Primaluna integrated and Focal 1008be2’s. Sounds great, but I’m getting a pair of Audiosensibility testaments soon. They are occ copper. I’ll post my impressions, however I love their power cords and interconnects. 

Wound up getting XLO sig3 speaker cable (have XLO sig 3 (XLR) from CDP to Pre & Pre to Amps) 1st thing I noticed was the Bass seems to really dig deep and the imaging was even more precise (seems to add vertical ques along with the already excellent horizontal ques). The mids-highs seem a little bit smoother (I first thought I lost some detail but upon further listening I realized all was still there along with some sounds I hadn't noticed before). Bottom line I'm VERY HAPPY with my purchase. (FYI..I have about 100 hrs. on them)

happy listening!
