Speaker cables Mid High end

I agree with the Fidelium Speaker Cable.
Ultra High End sound at a Mid High End price.
With the 30 day return policy, you would regret not trying them...

I would highly recommend that anyone searching for excellent cables to check out Luna, hand made in Canada.  I have a complete set (interconnects, power, and speaker) of their top level, Noir (black).   My electronics are top of the line Naim (500 Series) with the top Kuzma TT.  As each cable was introduced into my system, I was startled by just how much of a difference it made.  I won't go into the myriad adjectives available since the experience is obviously subjective, but suffice it to say, I could not have been more pleasantly surprised and impressed.  They make 5 grades so that regardless of budget, anyone can enjoy the experience.

If you want to broaden your search a fantastic cable to check out is
Thales Speaker Cable. They also make a great interconnects.

+1 Morrow. multi stranded and each strand individually insulated. whatever the science is behind that construction, i cannot say, but it works. 

I have auditioned the components you have purchased. I called ahead and ask if I could bring a pair of interconnects to try in their system and they agreed. They were using a lower end Audioquest that was not up to the standard of the components. After a short listen  we switched to the Synergistic Research Atmosphere level 3 interconnects that I had brought along. The difference was as expected Wonderful. The cable brought out what I knew Levinson was capable of and more! There are numerous Atmosphere 1st gen cables available used on Audiogon, Try a pair between the 2 new components and you will not regret it!
