10' speaker cables

I would look at Silversmith Fidelium speaker cables.  When I added them to my system—after trying about five different cables by Morrow, Audioquest, Raven, and Mogami, they made an amazing difference in the sound quality of my system … far more than I expected or I imagined possible.  They improved the tonal qualities of voices and instruments and yielded a three-dimensional sound stage.  The owner offers a trial period, so they are pretty risk free, except for shipping charges, I expect.

Different speaker wires have no objective difference in how your speakers will sound.

What about 14 AWG Mogami from Ayre AX-5 Twenty to KEF Reference 1s?

I have a nice 10’ pair of WyWires Platinum Series speaker cables if you are interested.
