Best phono stage for Lyra Etna SL cartridge?

I thought the rule of thumb was X10 the internal impedance of the cartridge, but that isn't the only factor- I'd like to know what associated equipment you are using, since you can, by the choice of components, voice the system through the. cartridge, phono stage/step up or other pre-preamplifier. I even ran one Lyra wide open with no loading at one point. 
I've heard Lyras on a variety of systems that sound great. I owned several pre-dating the Olympus. 

Technics 1200G, Kitsune phono, Don Sachs 2 preamp, Pass x350.5, Soundlabs M545.

Can you external load it and tryout some various loadings?If that works you be in for ~$15-20.

Your phono stage loading available ranges from 14ohms to 200ohm and 47k.
The cartridge can run into any load more than 10 times the internal impedance - so you can safely load it from 20ohms up.
What Lyra recommends is that you try all your settings and use your ear to decide. You should try it at 47k, then 200ohms. If your prefer 200ohms then try going down below 200 ohms one step at a time to see if there is any lower load that sounds better. If not leave it at 200ohms.
There are no rules because the optimum loading varies depending on the phono stage you use.
