Speaker cable for focal scala utopia


Hi, I need help with choosing the right cable for my focal scala v1 speakers.  I am currently using the Synergistic Research Element CTS. It is not bad but I want to tone down the brightness a little bit more if possible. I also have an opportunity to replace the Scala with the Magico Q3, should I take it?  Would it make any improvement?  the Any suggestion would greatly appreciated.  

Amp: Pass 100.5

Thanks for the suggestion M.  Have you try their Redwood or Firewood series?  I was told they also match well with the scala.  Are you using tube or SS?  I am using SS amp and tube pre. But I doubt they are the cause of my problem. 
In my experience, Purist cables have a smooth presentation, but without loss of detail, but I would finalize my speaker choice before making a significant investment in cables. 
I was using Audioquest Aspen before. the thunderbird is much better then the Aspen. Im also using solid state. The less expensive Audioquest William Tell would be very good as well. New series is more neutral, smoother and better detail then the older line. 
Havent really tried other brands. 
I also have a few Pad power cables (20th Anniversary) in my system which sounded great.  I thought about trying the Neptune cables but went with the Synergistic CTS instead.  I guess I will have to save up for the Dominus cables. Thanks for the suggestions guys.
