Actually you have 3 choices.
Upgrading your single wire cable is the third.
Which one is best is for you to find out.
Here are my experiences.
I changed from bi amping (with 2 x 4 mm2, silver/copper fine stranded flexible) to single wire 3.5 mm2 OCC Atlas Hyper that is double the length, because I needed to reposition my speakers.
Go to the Focal WEB-site, they explain why they don’t put bi-wiring terminals on any of their speakers.
In my case the Atlas Hyper 3.5, repositioning of the speaker and NAD M33 Eigentakt amplifiers provided:
- a homogeneous sound, meaning gray and precise soundstage and bass fundament
- better rhythm
- more detail without being harsh
I changed a lot, and it is impossible to tell of the change from bi-wiring (with bi-amping) to single wiring did all that. But I know for sure that the Atlas Hyper 3.5 (also made in Scotland by the way) are the best cables with which I ever connected my speakers.
For you I recommend that you inform your self about the pro’s and con’s. You can find con’s on the Focal WEB- site and so far, the benefits of singe wiring have been confirmed in my system.
By the way Atlas Hyper is also available in bi-wiring and you can have them interconnected with single spades or bananas at the amplifiers end if you need.
