Cardas Clear Speaker Cables?

Fellow Audio Fanatics - 

I currently use Cardas Cygnus speaker cables, which I really like. I am thinking about upgrading to Cardas Clear speaker cables. 
 

Can anyone share their direct experience between the two cables? What qualitative differences are there between these two Cardas cables? 
 

For a little more background, I alternate between two systems in my living room. A tube-based system: Conrad Johnson Classic 120 with LTA preamp and QLN Prestige Three speakers and a Gryphon 120 solid state amp with Dynaudio Heritage speakers. I didn’t set out to have two systems, but I appreciate them both. In terms of what I’m looking for with the cable upgrade, I’d like to bring a little more energy and drive to the tube-based system. 
 

Dac is Merason mkii and Innuos Zenith music server. Power cables are a mix of Cardas Clear and Less Loss. 
 

Thanks in advance!
