Optical digital cables?

Another option is to go to a commercial optical cable like what the internet providers use and have it terminated to your required size. These cables are very well made and made to an industry spec not to mention relatively inexpensive. find a local cable shop and ask then to cut and terminate a cable for your use. You do not need fancy audiophile optical cables go with the industry standard with appropriate specs

The Blue Jeans toslink, which is Mitsubishi ESKA, is just like all the other low cost mono-filament toslink cables.  It's basically a single plastic element that transfers the light.  These plastic mono-filament will sound dull and low-resolution compared to the better glass fiber cables.

The Lifatec is the best bundled glass fiber cable for the money.  If you're on a budget, buy the Lifatec.  It performs much better than Blue Jean or the other mono-filament.

Other alternatives are the Wire World Supernova 7.  Or, if you want to get really expensive, the Audioquest Diamond.  They are all just bundled glass/silica fibers, so I don't expect much difference between them.  Lifatec will cut and terminate each cable to your order (you can order custom lengths).  Wire World is a manufactured cable that comes in set lengths.

Thanks everyone,

I'm going to go with the Lifatec. I don't expect any sharp bends outside of the back of the KEFs to the back of the Node 2. I think I'll be fine with 20" but will go 24" for a cushion.

Good choice. I have both the Lifatec and the Blue Jeans cables. Not only does the Lifatec sound better but it will also pass a 24/192 signal, unlike the Blue Jeans which tops out at 24/96. 

I might be overthinking the length I need for the Lifatec. I can get by with 20" but was going to get 24" for a small cushion. Now I’m thinking what if I move things around later, should I get 36"? Any disadvantages in lengths this short? It’s only $10 more to go from 20" to 36" and I’ll have more flexibility placement wise down the road if I change things up.
