Need Opinions for Different Cable Manufacturers/Cable Designs

The Focal / MAC sounds like a great combo. I have heard them individually but not together. I would definitely recommend the best DHLabs you can afford in each category. I wouldn’t be too focused on the exact material components. In inexpensive cables the material determines the sound… but in better quality ones the overall design and construction dominates. Within DHLabs, I recommend the highest level you can afford. They sound better the higher tier… they have chosen the appropriate materials.

I haven’t done a lot of cable swapping, but I have heard enough to have a general impression of certain brands.  I like Audio Note cables—warm, harmonically rich and smooth sounding.  To get the kind of clarity you seem to want, their silver cables might do the trick, but the price is quite high even if you can find used cables. I use both their interconnects and speaker cables.  
Another brand with a similarly rich sound is Acrolink.  There copper cables have a bit more top end than Audio Note.

Of the brands you listed, I have heard, and like, Snake River.

For speaker cables, the Silversmith Fidelium cables sound very promising—detailed, but not harsh or thin sounding.

Thank you all for your comments. This is very helpful to me.

My experience with cables is that they can make a really noticeable difference, but I don' think I'd classify that difference as "vast".

I will say that one cable that sounds great in one system may sound horrible in another.   I love my GR-Research cable in my Xstatic-Krell rig, but it sounds really weak in my Totem-NAD system.   I found the Cardas Clear to be a good match in this system.   I really liked the Chord Epic Twin cables in with my Xstatics when I was running a PrimaLuna HP Dialogue Integrated with KT150s, but not once I upgraded to my Krell K300i.

This is all to say, that you have to experiment and listen to cables just like you do components.   Synergy is everything.   Buy new with return policies or buy used and resell what you don't like.   The good news with cables is that there are a lot of options out there and if you play it smart, there is very little financial risk.

Have fun and enjoy the music.

Buy used Audioquest Earth XLR interconnects, and JPS Labs Superconductor 3 speaker cables, and thank me later!!!  Happy listening.
