Speaker cables with good timbre

The cable Devon Turnbull sells on his Ojas site is really excellent. I think it excels at the qualities you’re looking for. It’s not terminated but I can’t imagine you’d find better anywhere near this price. 

Audience AU24SX or FrontRow. They have a natural tone, are highly resolving but never bright. I tried many speaker cables and the FrontRow are by far the best I ever heard.

I have 2 sets of these, and I concur. My Magnepan Mini (and LRS+) did not seem to benefit as much as all other speakers with the FrontRow.

I did a comparison with the AU24SX and the FrontRow speaker cables. If your system is very resolving then you can hear some harshness with the AU24SX, nothing bad on the FrontRow.

I use a 10 AWG speaker cable from Blue Jean Cables for the Magnepan Mini. One set of my FrontRow speaker cables sit idle for now.

I was at the same point quite a few years ago ... looking for speaker cables with great timbre. Auditioned a number of brands over about a 3-month period. Installed Gregg Straley Reality speaker cables, got off the merry-go-round, and never looked back. Note: they're still in business but have not updated website in quite a few years (says "Not Secure"). YMMV

Happy Listening!

i would buy and make your own the GR research cable kits superior performance yet low cost ( a pair of 4' are i believe less than $100! ) 
they will surpass most all others 

I’ve used cables from Blue Jeans and SVS and Audioquest (because it was a great one-time deal). Recently purchased my first cable from Pine Tree Audio in Fitchburg, MA. Locally Well made with a lot of choices including color, which is fun, and reasonably priced. Check out their rainbow ribbons. Very cool.
